XRite.com has a test at their website where you can see how well you can distinguish between very similar hues by arranging color chips in a smooth gradient from one color to another. The color ranges used are ones which the human eye has a hard time distinguishing from one another — basically somewhat washed-out or muted pastels. The lower your score, the better you are at telling similar hues apart.
How did you do? What is your Color IQ?
Mine was zero; according to the test I have perfect color vision. Of course, I also have a good-quality monitor for my computer, which can affect the test. I guess all the web design, not to mention the lampworking, has paid off.
I got a 9. My monitor isn’t as good as yours … but it’s also a function of genetics. Almost *all* of my mistakes were concentrated in the boundary between green/blue. My father was color blind, and I carry the gene for it. My sister makes the same mistakes, but whereas I will see things as more blue than they are, she will see things as more green. Ain’t genetics fun?
