I don't know what the value of this is, but I'm relieved to have scored a 3; I'm an engineer with an emphasis in spectral reflectance analysis. Heh!

I scored a zero! Tetrachromats for the win! :)

19, but i'm not complaining.

it would have been nice to have it break down where my blind spots are, so to speak, though.

I scored a 4. @PHIZZLED On mine it gave me a chart after that showed where my weak points were.

I scored a 3! I knew exactly where I was having trouble. I have a pretty nice widescreen monitor, but I would have liked to have taken this text on a REALLY nice monitor.

I scored a 3....and here I always thought I was terrible at picking out colours

I scored a 7 but some some reason my colors looked way more muddled than what is shown above, and also the row wrapped around to a second line!

I scored a zero as well. I have truly terrible eyesight and have always felt lost when picking paint colors, so that surprises me.

I got an 11 which isn't bad for a guy whose mother SWORE he was color blind as a kid! I kept trying to tell her I just wasn't fashionably inclined. I think I would've done better but my eyes started to pop from staring too carefully at the screen (I get double vision thanks to my doggone eye muscles.)

Still, I think I did pretty well. :)

I'm a lady and scored 89. I was just discussing this morning my problems with seeing colors.

welp, my eyes are now killing me. I scored a 37 because of the crappy monitors at work, but i will retake it at home and see if that makes a difference.

Neat. I got a 6, and by the end my eyes were all messed up.

I scored 385. I am (*)(*)(*) (*)(*)(*)(*) colorblind. And I'm a girl. I can't tell brown from black, so I have no brown in my wardrobe.

3 for me!

I scored 29, but you know what, you can't miss what you don't even see. When I looked at the spectrum after organizing it, they all looked smooth and transitional to me. I guess if someone next to me had better discrimination and was looking at it with you.

I got a 4. Not bad on an un-callobrated monitor in bad lighting. I'm going to take the test at home and see if the results are different.

Ok smarty pants crew. Now for the difference. I was,, well into the hundreds, now to start,I am an industrial design, but I have confirmed color blindness. The issue isn't nearly as simple as the test shown however. While I'd love your color vision (and am currently clad only in black, however it's a T-shirt and shorts) there are distinct differences in this test that make it harder or easier depending on the type of color blindness as well. To properly complete this test I believe I could get within 50, but the real issue is different types of colorblindness give profoundly different results, as do proximity to a nearby color. Hue is different than value. On the other hand, it's good to know what you see is "approximately what others see". Remember, you are only agreeing that the gradient choices shown follow a range that travels from 1 direction to another. (It is a well designed test by the way congrats to whomever did it.

Does this work with an iPad. My iPad IQ is probably close to a 900. ;)

I scored an 8 myself. Time to send this link to my husband to prove I know what sofa colour would match our living room the best.

Got a zero. Very surprising.
It's kind of strange that the results page doesn't show an average for your demographic, just the highest and lowest.

I've done this before and got a really low score of 2-4. This time I took it again and scored a 4. There are some lavender to coral colors that I swapped right in a row.

This is so cool! I got a 4, which was better than I had anticipated. Though I guess I am sensitive to color and undertones. It showed my trouble spots as the blue/green area, though I had the hardest trouble with the orange. Neat!

86 for me. Buh.

I don't know why anyone would care what my score was but I have so few external measurements these days I stayed up way past my bedtime the other day to get the high score on that TiVo scrabble game. So HA! I got a 6! SUCKIT!!

I'm going to blow my daughter away when she gets to Montessori color box # 3!

I got an 8. Not bad.

I scored 41.

I have a parent with color blindness and have always gotten at least one wrong on the color blind tests that we took in elementary school, with a number or letter composed of circles mixed amongst other similarly colored circles.

Yikes, I know I'm legally blind, but it's still distressing to get a score of 279.

Scored 16. What was interesting to see is that the spectrum "problem areas" for me when the tones that were used more in the two tests on the bottom. I just chalk that up to proof that my eyes got tired of doing this test as I progressed and made more slip ups, rather than my ability to truly differentiate hues.

I scored an 8 as well. Guess there is a reason my mother always asks me to help pick out colors for decorating!

Perfect score? I'll take it! A tip for people who haven't taken it, or want to retake it - set them up quickly, take a break, and then go back to them, make some adjustments, and try going down the line, swapping two cells at a time. If there's a difference, you'll notice it more when you're focusing on just one 2-3 cells at a time.

Man, my eyes hurt...

Yay! My score was zero, thank you Dad. If you're dealing with hues, does the monitor quality matter? I think mine is an average widescreenish monitor.

Got a 0. I'll be bringing this up next time I tell my brother his favorite T-shirt is green, and he swears it's blue. Good reason to have an extra X chromosome.

I wasn't surprised that I scored a zero since every single one of my art teachers has told me that I obviously see colours others don't. When I look at a colour, I can see all its parts and can replicate it. I also have apparently amazing colour memory--I can buy something, be it paint, artwork, towels, etc., and have it match something at home perfectly.

I scored a 4. Not too shabby for a graphic designer in a rush.

Also, I wasn't wearing my glasses.

I scored 24 but I thought I would go blind when doing the test. I am sure really what the score reflects more my colour acuity or the crappiness of my monitor?

Bam! Zero! I win bragging points!

But seriously, that was a fun lunch-break activity :)

My eyes hurt :(

zero! not bad! I found it helpfull to take two short (1 min) breaks.

19. wtf?

Oooo, I scored a zero! For some reason this actually makes me feel really good, lol.

Wohoo! I scored a zero! This made my day haha :)

zero... but my eyes hurt now. haha.

26. I'm at work and did it quickly. I'll try again when I get home.

Hey designers - would this be considered a legit test if one were to apply for a position that required proof of "color acuity"? Does anyone have suggestions for something like this? Thank you!

Doesn't work on an iPad? Bummer.

i scored 4 and husband scored 19. i suggested that next time he says, "that's blue" and i say, "no, that's grey", he should defer to my greater colour sensitivity. his response: "no, it means you have to stop asking me what bloody colour to paint"... fair enough.

I scored a four, but darn it, I wanted a zero. The blues killed me.

I got 15. Surprised I did that well. Have never worked in any area of the visual arts, though I can match my own clothes pretty well.....

Did it on my Mac and got an 11 (blues are my weakness). My old eyes were having fits looking at the screen, though. I'd love to try it with real color chips.

I'm glad I don't have to drive anywhere soon because I am still seeing spots.

27... and now my eyes hurt. I'm surprised it wasn't lower. I always thought I had a good eye for colors.

8! Woohoo! The blue was ridiculously hard.

Now back to work...

I do wonder about the accuracy online - I took a physical version of this test & they had the test takers sit in a "tent" with a specific color balance. In the physical version (at a CMG meeting) I think I scored a 2. (You could never score a 1 because if you had one tile in the wrong spot, two tiles were actually swapped.)
I just took the online version very casually & quickly, with the sun glare hitting my monitor... and scored a 7.

I got a 3! Pretty excited!

0! Maybe this is a sign that I should leave the legal profession.

Dayum! I got a 0. With a bad monitor and bad lighting. It took me quite a while, though.

And I always felt like I had the hardest time distinguishing between "pale seafoam" and "greyish aqua".

I got 4, too!

Add me to the 3 club, but I find it funny that my misses were on the blue/green line (since those two are my favorite colors).

It think the quality and calibration of your monitor would definitely have an effect on your score, also, I found it helped to adjust the lightness of the monitor. On the brightest setting especially I could not tell the difference between two colours anymore.

44, and i thought i was doing well!

I'm intrigued by the high incidence of low (aka, near-perfect) scores in the comments. Is it just that people who get worse scores are less likely to post, or does a design blog like this one tend to attract people who are more sensitive to, and thus interested in, color than the average person who does not read design blogs?
I'm also super-excited to see someone refer to tetrachromats--I just heard the Radiolab on this one! Cool!

It took me about a minute per row, and I scored 0. It seemed very obvious, and I doubted that the test was for real until my daughter, who sent me the link to the test, directed me to this page. She also scored 0, though she said it took her awhile to do it. I find it intriguing that it isn't obvious to everyone since with few exceptions, it was instantly visible when a color was out of sequence.

I scored a 15 on a crappy monitor. I'm pretty happy with that, but I wonder if I would do better with a better monitor.

Scored a 4 on a terrible work laptop monitor. Fun experiment!

Got a goose egg. It was harder than I thought it would be.

I had my red/green blue/yellow colorblind husband take the test. That was fun. He was basing some things off of dark to light..I think he scored around 80 something. Despite the score, he had the colors lined up in the generally the right direction.

I scored a 4... slightly disappointed, as I am a graphic design student who should be very sensitive to colors displayed on a monitor... oh well. It was the teal range that got me. My eyes are killing me now.

@Happy Spirit -- congratulations and all, but you aren't being very gracious about it, are you.

Holy crap that is hard on the eyes! I felt like I was on acid.

Scored an eight. I slipped a bit in the blues and in the purple-reds.

score 12, age 46, woman. Satisfied.

Given the statistically illogical number of good scores reported here, this "test" doesn't seem very accurate.

Going in I knew there was cat saliva and other gunk on my glasses, and really, I just didn't have the patience to fine tune my choices, but I still ended up with a 14. The interesting bit for me was that I seemed perfect except for two areas. One of those areas is my least favorite and I would've predicted, but the other encompasses my favorite color-range. Hmm. I wonder if this knowledge will be useful or if I'll just forget it...

I got a 14 and am over 50 years old. I was actually proud!

Well the statistic seems illogical to you because it is not an accurate representation of a population as a whole. It is limited to the scored of only people who love design, read apartment therapy, and those who actually decided to post their scores. As for the efficiency of the test itself, as a reliable judge for colorblindness I have no idea, but theres no need to be a bitter betty about it.

I got a 4 the first time, then tried again in the morning taking pauses in between each row to stare at white walls until the afterimages went away. That time I got a 0.

Woman, late 40s.

I wonder if I can get my graphic-designer husband to take the test.

0. This was on a hp mini 2140 netbook, which has a 10.1" display with 1366x768 resolution. I wanted to know what percentile this puts me in, but I guess they can't account for ppl taking the test multiple times. I didn't really do anything fancy with resetting my eyeballs or anything, but I did something like an iterative sorting process after the initial round of sorting to double check.

I got a 4. Problem area in the teal/aqua. Setting up my art school fiance to take test now...

I'm not sure I did the test right. I got a 131. Most of my answers were correct. Oddly enough, the colors I did the poorest on where in the green shades--a color I do not like.

Wow, I got a 71. Did anyone else get really dizzy doing this?

Hey Sean, please do your home work before posting your article. Color blindness and color deficiency are two different things. Color blindness, achromatopsia, means that someone can only see things as black and white, or in shades of gray. This condition is EXTREMELY rare. Color deficiency refers to someone who can only distinguish certain shades of color.Your opening sentence should state that "1 out of 255 women and 1 out of 12 men may have some degree of color deficiency."

These common misconceptions are actually a big deal to people that are color deficient. We can be passed up for jobs because of misconception that a "color blind" person cannot see colors and therefore cannot perform the required job. The military, law enforcement, coast guard services, firefighting, engineering, pilots, railroad engineers, scientists, and many other job providers can legally discriminate against color deficient individuals. A person with red/green color deficiency can still see red and green. There might be difficulties distinguishing the two if the color shades are very light or very dark. Most color deficient people can still tell the difference between a red stop light and a green light.

Zero, baby! When I worked in design, I could usually eyeball the right Pantone colors; now I know why. Took the test on an older monitor, with no glasses, & I'm F/40s.

So, without disclosing how disappointing my score was, is there any way to improve?

I got a 0, but people always tell me that they think I am colorblind. I can't mix and match colors for my life.

23 for me. I have been worried about my color acuity so this was quite helpful. I am a 60-y.o. female wearing trifocals, who sews a lot.

Wow. I can't even finish the test since so many of the colors look the same to me! But I always knew I had color deficiencies. Maybe I'll try this later when I feel like racking my brain!

I do find it odd that some people are proud of high scores. Surely it has more to do with genetics and discerning color as opposed to some sort of talent, innate or otherwise? It's like being proud of being tall or having green eyes or something.

I have dual monitors. On the crappier older one it was a 8 and on the newer one I got a 3. My eyes are burning so much right now, maybe I shouldn't have taken the test twice in a row.

Whoo hoo. I scored a 4! Finally I can prove to my partner (graphic designer and photographer) that I DO know colors! Ha.

Btw, he has yet to take me up on my challenge to see if he can beat my score.

Oh and OUCH. My eyes were killing me after I did this.

Took it at work and got a 24, but my work monitor is pretty horrible. Took it again just now on my 4 year old macbook and got a 3. I'm pretty happy with that. Would really like to see the curve though.

I first took this test when a friend posted on facebook. I wonder how a real
v would fare on this test...and what to do about variation in monitor calibration?

Got a zero! Feeling like I can accomplish ANYTHING now :)

I wish they would have put some sort of statistic of errors relating to monitor calibration. Not all computer monitors display exact true colour and unless you calibrate your monitor (for example if you work in graphics or photography) you might be off.

I scored a 16 - I according to my demographics, that seems pretty darn good. What I didn't like is their use of explanations:
Best score for your gender and age range: 0
Highest score for your gender and age range: 1520

To Me - Best and Highest mean the same thing - they should say something like HIGHEST and LOWEST of Excellent Hue recognition and Poor Hue recognition

A friend did it, scored a 44, and told me the test took her 'ages' to do. I wish that the test tracked how long it takes you to complete. I got a zero and spent about 15 seconds on each row. For the other zeros out there, how long did it take you to get your score?

Scored 4. I was a bit surprised by that score; I thought it would be much lower (or high, I suppose).

Don't forget that the quality and settings on your monitor will play a big part in your success!

@phizzled They DO break it down for you , as to where your blind spots are. Right underneath your score there is a spectrum and the problem areas are highlighted.

I scored a 4 (surprisingly!). I enjoy color but don't see that I have a very distinguishing eye, until today! I suppose I need more work with (or just need to avoid) the muted olive greens/yellows section. I've asked my husband (a photographer) to take the test so we can compare scores!

Everyone who commented here got VERY low scores, at least for those in my age group (I'm an "old lady" of 61.)The lowest score for my age group and gender was "0" (of course) the highest was 1520!! So, with an 11, I'm not dissatisfied at all..
Also, as many others said, my test showed me where my color perception was weak and also gave me a comparison to others of my gender and age.

I scored a 0! I have "Perfect Color Acuity"!!

I am proud.

I scored a 4, and the very colours [greens] where I stubbled to sort the colours were the ones were my colour acuity is lower. Interesting.

Well I pride myself as a colour nerd, so I thought no problem. It was14 on my first turn and I was cranky about that, so I did it again determined to do better which resulted in a 16. *pout*. It is a little head spinny...more so, as I have double vision AND was talking on the phone. So I think I will go back when I am not on the phone and my eyes are fresh and see what the score is then. ( obsessed much? )

I think there's cause for concern when you're a 17 year old girl who scores a 46 :/

I scored a perfect 0. I have wondered for a while if I'm actually a tetrachromat and this just adds to my curiosity.
My boyfriend scored very well too with a 6. His only problem area was right in the teal and turquoise shades, which is funny since I used those shades heavily to decorate our apartment. Maybe he's just overdosed on them in our living room. Haha~ This is super interesting all around.

15 and I rushed through it because I have an old (NOT FLAT SCREEN!) monitor and my eyes were dying.

40 yo female. My dad is color blind, as are both my sons. One son has it worse, though. They struggle with blends of red (orange, violet, brown, maroon, pink, lavender etc.).

Ow, my eyes.

Got a perfect score. I went to high school with a kid who got a perfect 1600 on SAT and know 2 people with perfect pitch but isn't this ability really so much better? Feelings of superiority validated. No seriously, this is interesting. I'm an fiber artist and I love using color. The hardest paint mixing challenge is to get black from mixing red, yellow, and blue. More difficult than you would think. It's cool to have high color sensitivity but the ability to see color or lack there of doesn't determine artistic ability. I had a boy in one of my classes that was colorblind (but maybe he meant color deficient) who did an amazing acrylic painting with a beautiful use of color in which everyone could clearly see his talent. The comments and test also make me think of Shades of Grey by Jasper Fforde (not the infamous 50 shades of grey but an entirely different book) about a society where color sensitivity determines social ranking. I apparently would rule such a society with my amazing color vision ;-)

I scored a "0" !! :)

The ability to correctly arrange colors doesn't have a lot to do with your ability to decide what colors work in a room or a design per se....

For me, I'm nearly legally blind, have been since I was 4, I'm in my late 20s now and I've always sworn I see detail through my acute perception of color because I can't actually see with any level of sharpness... think high def tv vs monet painting... I scored a perfect score on this test.

I think for me, my ability to see color makes up for my lack of clairity in my vision, so perhaps you all with "poor color" aren't actually so bad, it's just that your eyes see detail well enough on their own, that they don't have to perfect the slight nuances in order for you to perceive depth or space.

hmm... I think I did it wrong. I didn't understand what the one color block on the second line was for

I was nervous to take the test because I always brag about my colour discerning skills. I was hoping to do 19 or better. I was very suprised to find I got 0 considering I didn't think I had answered it correctly.

Yay! I think the monitor makes a huge difference. Scored an 27 on my MacBook Air at home, but a 7 on my Dell monitor at work. Hmm... interesting.

Guy here...designer....47 years old....scored a 3

Got a 4 but was crosseyed by the end.

Thaaank you for posting this! I've had to defer every color argument I've had with my husband for the last seven years. Since he grew up drawing & painting, but I grew up playing music, he thinks he is the obvious authority. I scored a 0 and he got a 3, so he finally has to stop badgering me. This is life-changing! ;)

While this test does test how well you distinguish between different hues, it does not test how you name said colors or how you process said colors. Just because you perceive a color to be blue or grey or brown doesn't necessarily mean that another person with a high ability to distinguish between hues will perceive it as the same "color". The arguments about whether periwinkle is more blue or more purple will still continue even if you can distinguish between a slightly bluer or slightly more purple periwinkle. That is, unless you take out the spectrometer and precisely define in wavelength where purple ends and blue begins.

A "0" for me too, which I found interesting. I have known since taking Colour Theory in Art School that I had perfect colour, and like another commentator, I too can remember colour like other folks remember music or languages. I have noticed that as I age, now 41, my memory of some blues is off by a smidge at times. I was so curious to see if I still had it! I guess I do, even if my ability to memorize colours is not as pitch perfect as it once was.

And like someone else, my husband can never argue with me again about what goes with what!

I deal with colors for a living, day in and out, and every place I work this test has been passed around .Every time I get a perfect score. I just have really good color vision. Always have (hence what I do!)

But my husband, who is blue/yellow color blind, does the same work as me and he scored in the 60s. Just goes to show ya.

I got an 8. I looove stuff like this. Thanks for posting, AT!

Hi, Travelingrae,

I didn't think to time myself, but I did it about as fast as I could move the squares, with a little additional time to transpose ones that seemed close just to make sure I had them in the right order. Switching ones that were close validated most of my original sequence.

Hi, Sunnyblue,
I am also a woman, 65 years old, just now retired from a lifetime of teaching--hooray! Like you, I love to sew; during my working life, I tailored my own suits. Don't know what I will sew now except dance skirts and dresses. :-)

The test measures only hue discrimination; there are other color scales, like gray scale and saturation scale--and probably others that I don't know about. I've never studied art, but I spend a lot of time trying to match fabrics!

I got another perfect "0" score. Heck it's Monday morning I will take whatever validation I can get! Plus, I've always secretly suspected I had really good color sense. I once got offered a job at a MAC counter by re-directing a fellow customer's lipstick choice to one just SLIGHTLY different but so much better for her skin tone, ha ha!

Even though I compose outfits and room arrangements that blow my friends and coworkers out of the water, I apparently don't actually see color particularly well. 68!

So being a brat and throwing a little tantrum, I tweaked the monitor brightness and contrast and took the test again...67. Almost as bummed out as getting 131 on the Stanford-Binet.

Oh well, I'm still a good person! My cat loves me! ;-)

Oh my gosh, I got 4! I'm so happy. After staring at the screen so long the colours started to look funny and I didn't feel like I could distinguish them anymore, haha. I've always felt like I was good with colours, so I'm very pleased with the result.

The scores are pretty useless because it depends on your monitor and color settings. I got a 12 on my Macbook, and a 64 on my Vaio. I've adjusted my Mac settings because they tend to not do well on the darker end of colors. The Vaio I'm using the color settings from the factory. So yeah, It's better to take the test offline. All this is pretty much telling you is how good your monitor and color settings are.

Tamarind- Not really. It doesn't matter the monitor, you'll still be able to perceive the color differences just fine. If your monitor shifts more to magenta (many do) then you should be able to see differences just slightly more pink. The values of the colors are always going to be visually difference, no matter what your monitor is, it may just skew more towards one color or, in the case of Macs, they tend to be about 10-20% more lifted values than a non-Apple monitor. Even if they were printed out to arrange, it would vary printer to printer. Your eye can still discern a slight difference.
I've done this test on at least 5 or 6 monitors and aced it every time.

i got a 48. :( blaming it on my crappy monitor! ;)

@Happy Spirit. Congratulations on your retirement! (whew :) If you love to sew, you might be interested in sewing little pillowslip dresses for this organization:
http://www.littledressesforafrica.org/blog/
They also take simple little shorts for boys, and while the organization started out sending the dresses to Africa, they now send them all over the world, including needful places here in the United States. I am amazed by the variety of dresses I see in the photos.
Best wishes, SunnyBlue

0 yaaay!

A friend of mine is pretty colour-blind and whenever he mentions it people always say "Really what colour is this sweater, what colour is that book? etc."
He always replies that you wouldn't ask a person with one leg to hop for you, so why draw attention to his disability? It's funny that people are fascinated and have no distance where colour-blindness is concerned.

Fun test. I scored a 4.

Wow!!!!! I must take this on a different computer to compare....

28 for me. Eeeeeh.

I scored an 8, and I'm 24. Satisfied, but I'm not going to lie, my eyes are terrible. In contacts, I wear -9.5 and -8.5. I'm wondering if poor eyesight plays any role in this. I totally am seeing floaters now that I've stared at the screen for so long, hah.

Am absurdly pleased with my score of zero.
But with my forty-something-year-old eyes, I had to zoom in so I was dealing with larger blocks.

Got a zero. Had the hardest time with the khaki to green one.

But SabrinatheDestroyer has the method down. Swap two at a time to check for differences.

I got a 234. :(

I have a mini computer and maybe I'm slow or my computer is different but one color had to be on the next row down and I matched it with the left color. I was surprised to have a 91. So I did it again making the bottom color match the right side and got a 7. Maybe someone surprised by their high score mixed up the second row like I did?

0!!! I always defer to my husband on color issues since he is a colorist, but it looks like I am actually the master :) I am female.

Thank you, SunnyBlue. That's a lovely idea.

115 but minne also wrapped to a 2nd line and I wasn't sure what to do with that... there was just one block there and it was moveable, so it wasn't either beginning or end.

I got a 20. Mine wrapped around too, but I just assumed that the square on the bottom was the second to last one.

Also, it seems like the test should be timed. I didn't want to spend too much time on it, but it doesn't really seem accurate to compare my score with that of someone who took 15 minutes on it...

I was surprised by my perfect zero score. Hooray me! *high five*

I'm a 23/f and I scored an 8. If I had taken a bit longer to do the test I might have been able to eek out a slightly better score. My problem area was the teals. Not surprising, since that's definitely where I struggled the most when sorting.

Awesome! I scored a 0....
I'm 35 and a dude

Scored an 11, but I have a terrible computer monitor - every chip looked muddy :( Will try again someday on something pretty... I'm 31 and a female

48 year old male and I scored a zero the first time! My girlfriend scored a 28 and I went and fixed it and got a three that time.

W00000W.
First time I got 30 because I didn't pay attention enough but the second time I got 0.
20 year old male.
Here is the screenshot,I used paint(:D) to write my nickname(Hotsun)and first name(Payam) don't be shocked when you see that ;-)
http://s1.picofile.com/file/7493535913/Color_IQ_Hotsun_K.jpg

21 -doesn't surprise me. Many of the swatches looked like exactly the same color to me so arranging those ones was a real crap shoot. I have trouble with gray/green -so does my husband.

29-year-old woman with score of Zero!!! I'm not surprised either because I've always been able to tell hues apart. This just gives me more ammunition with my family. They've always told me I'm seeing things. lol. Guess I am!

Well my initial score was a 119. I decided to wait and retake the test the morning and scored 137. I know I have difficulty distinguishing between blues, blacks and browns, yellows and greens, pinks and reds, but I figure its normal. My husband says Im colorblind oh well I grateful I can see :) lol Fun and interesting test

I felt deliciously smug to score zero too. I'd welcome more detailed statistics: percentages for score/age/sex so I could feel possibly even smugger about nothing clever I did.

BOOYAH! Zero! i feel awesomely awesome. not as awesome as watching doctor who marathons, but a close second! i got zero! Tetrachromats for an absolute win!!!

I took it 3 times to test out some stuff. The first time I got an 8 (normal circumstances, all at once and rather quickly), then 7 (while leaning sideways standing up over someone else who was sitting in front of the computer, lol very uncomfortable and rushed), and I realized that when staring at it for too long it starts to cause a blurring effect that makes the score less accurate, so the last time I decided to take breaks between each line to ensure my eyes were at perfect health and I got a 0.
I could tell a huge difference when I took breaks, the one section I had problems with in the first two (third row down, left side- greens), I could now clearly see the variance.

I definitely recommend taking breaks each like for just a minute or so. Or every other line.

I guess that's why I work with color professionally as a designer. -_-

I got a 12 and a headache! The light above the computer monitor is so bad, though, that I sometimes have to take yarn outside to see what color it really is. I'm going to take the test again when the LED light bulb I ordered for the lamp arrives. Still I did better than I thought I would.

One of my sons (the other is not) is color blind...red/green deficiency. Since my father was not color blind, I must have inherited the gene from my mother. Since my son is color blind, he got the gene from me and, should he have daughters, will pass it on to them, and they will be carriers who could have color blind sons.
