Are You Colorblind?

What colors do you see in the picture above? To people with red-green colorblindness, the colors on the left and right sides mirror each other. Red-green colorblindness is common and results in red, green, and orange looking like muddy shades of yellow and purple that looks bluish. About 1 in every 20 people has it. We can see color thanks to the receptors at the back of our eye that pick up light. The typical eye uses three kinds of light sensors, each detecting different hues. Colorblindness could be caused by a missing set of receptors or out of tune ones. Colorblindness can result in off-limit jobs or activities. Researchers have recently created glasses to help with this problem. Maybe one day a lack of color vision won’t be an issue at all.
