We know that color perception is an individual matter. We will never be able to look through someone else's eyes, but we can test how people label colors compared to each other. The language we use for colors affects these tests greatly, as color names vary over time and by culture. The site Is My Blue Your Blue? offers a test to see how you label shades of blue. Your screen will show a color, and you click on your opinion at the bottom. The shades will get closer and closer until your perception can be plotted on a graph along with the results of others taking the test. This test only distinguishes blue from green; now I want to try this with other colors. My results ranged from 174 to 177, depending on the time of day. Others say it also depends on your screen, the lighting in the room, and whether you have undergone cataract surgery.
By the way, if it tells you that turquoise is green to you, remember that is just a color sample, and has nothing to do with the rock. I have both green and blue turquoise jewelry. -via Metafilter
