Colorblindness

[asterroc]

While surfing the web to try and find the appropriate html code for maroon, I stumbled on this list of consequences of colorblindness. (I think it was on the same site as the second hit for "html css color name".) I'm sure if I'd thought about it I would've come up with how it'd be a hinderance in reading various chemical tests (I do teach science, after all), but it never occurred to me that you might not know whether you have a sunburn, or that single blinkie lights are unidentifiable.
