One of my fellow work shop / photo op participants from last year, Marc Gaudet, posted a link to a site for testing your Color IQ, basically testing your acuity with distinguishing colors as they change hue from one to another. The test is rather simple, yet extremely effective.
Marc scored a 4, with zero being perfect and scores above that being worse and worse …
I scored 54 … no doubt a product of my color deficiency … and the kicker is that the four bands looked pretty smooth to me. But obviously that’s the point … color deficiency is a problem that does not manifest itself until it is tested.

Go try it out … it’s fun and very informative.
Update: On my fairly new Dell U2311H eIPS panel, I scored 39, and my errors were clustered a bit tighter. Definitely an obvious pair of areas where my hue discrimination is atrocious.
