I found a link to this on one of my favorite blogs and enjoyed the challenge. It is a hue test, it tests your "hue discrimination"(how your eye perceives change in hue) . I proudly scored a 4 and ironically have lower hue discrimination in the area of my favorite colors-cyan, periwinkle. You arrange the hues between the swatches on the ends. Then it scores you, the lower the number the better. What did you score? Leave a comment!
