X-Rite Challenges Your Color IQ
Their online color test - a version of the same FM 100 hue test used by government and private industry alike - gives you a chance to see how well you do on your own. According to X-Rite, 1 in 12 men and 1 out of 255 women have a color vision deficiency.
The test is fairly simple to take, but don't confuse that with easy. All you need to do is drag and drop colors to arrange them by hue.
You can try your hand - and your eyes - in the X-Rite Online Color Challenge.
