The Farnsworth Munsell 100 hue test was developed in the 60′s as a means to test ability to perceive color. You can buy one from Pantone or any other large color company for about, oh, $725 OR you can take it online from this site for free! If you have a few minutes to blow, it’s kinda fun (assuming you don’t go crazy in the process of dragging the color dots around.) Taking this bad boy while intoxicated may not be the best idea.
Once you’re done, this site will score you and, based on age, tell you how you fared. Considering most of you folks are artists that work with color in some way, you should do pretty well! Enjoy.
