Good call. The Farnsworth F-100 is an excellent way to evaluate color vision. As it turns out, I'm a complete deuteranope (I am missing 100% of my middle-wavelength cones). My classmates used to have a lot of fun teasing me about my F-100 scores.
Another good test, probably the best test, for color vision is to use what's called an anomaloscope (
here's an online version). However, these instruments cost a couple to a few thousand dollars and are usually only found in research settings.
Incidentally (and this is directed at no one in particular), very very few people are truly color-
blind, in that they see no color whatsoever but only shades of grey (whether it's 50 or not depends on if they're into S&M). These poor folks are called
rod-monochromats, and, since they are completely lacking cones (cones provide for not only color vision but also for acuity), they have severely reduced visual acuity as well. 99.9% of the population who are called (or call themselves) color-blind are actually color-deficient.
