It is generally believed that around 1 out of 255 women and 1 out of 12 men may have some degree of color blindness. When you consider the importance color plays in the products we buy, our aesthetic tastes, and the design decisions we make when we decorate, it's quite intriguing to consider that many of us likely don't perceive colors the same way.
X-Rite, a company that specializes in the technology and science of color (and who also owns the popular color system Pantone) offers a really interesting tool to test your "color IQ" online.
A series of subtly varied color swatches ranging between two hues is presented out of order, and it's up to you to rearrange the swatches so that the gradient between the two colors is correct.
Upon completion of the test you're presented with a score on a comparative scale based on your age and gender. Having worked with color most of my life, I've always thought myself to have a very astute ability to judge the subtle differences between hues. On a scale between 0 and 99, with 0 being Perfect Color Acuity and 99 being Low Color Acuity, I scored a 16. Though I'm glad I scored nearer the Perfect Color Acuity end of the scale, I was a bit disappointed I didn't do better.
It's quite an interesting test, especially considering some people have passed the test with a perfect score. Some of you out there might be lucky enough to see more colors than the rest of us! That's an interesting prospect, isn't it? I recommend you go take the test yourself and let us know in comments how high/low you scored. Who knows, maybe you're one of the lucky few who experiences a richer, more diverse world of color.
