Red? Green? What's the Difference!: How Color Blind Are You?

Picking paint or fabric colors can be a real test of one's patience. Especially when you are trying to come to a joint decision with another person. When mulling over wall color options with my mother recently I started to feel like we were actually seeing our own subjective and unique versions of each color swatch; as if the color itself was less an objective reality and more a subjective projection. Well, it turns out color actually is subjective.

I discovered this at a children's museum (ScienceWorks) in Australia last month (yeah, that's sort of embarrassing I guess), I learned that color is a "sensation" that is created by your brain and that not everyone's color perception is the same. We all have difference color receptors (called cones), which send messages to the brain when stimulated by different wavelengths of light. The brain then creates the "sensation" of color you see.

So I started to think about color blindness, a condition that would certainly change your experience of color! Ever wondered if you have mild or moderate color blindness? Well, here's a super fun self-test called the RGB anomaloscope color blindness test, which can be found on the website colblindor, created by Daniel Fluck of Zurich. The test is not a substitute for a real anomaloscope (because of the three color limitation of computer displays), so if you suspect you have issues it is best to see an ophthalmologist. But this online test does help predict the severity and type of red-green color blindness.
