I just found this website where you can find out how well you can tell colors apart, in other words, you can test your color IQ. I’ve used Photoshop quite a lot, and I thought I had a pretty good eye at telling colors apart,etc. well I thought right, it’s not pretty hard actually, just order the colors in hue order, and that’s it, according to the test I have a perfect color vision, which means i scored 0, and you??, do you have a good color vision??
