Actually, we do get the color-blindness test here.

Subject: Re: [Histonet] Interesting discussion about RE: timer calibration
Sure, why not? Require all histotechs to pass a "color-blindness"
(note the quotes) eye exam. Given that women generally have better
color discrimination than men in the red-green end of the spectrum,
female histotechs should be more valuble and able to demand higher
pay.
I can just see medical supply houses all carrying Pantone color charts ...
