As I’ve been looking up more and more on accessibility (section 508 guidelines etc.) for some site redesigns, I’ve become increasingly aware of some of the other issues around it, and finally read up on some dedicated sites about the different types of colour-blindness.
I think I’m deuteranomalous – i.e. the rods in my eye don’t perceive green as they should. The intensity of light is still the same, but the waves are off-centre. It’s not that I can’t see green light (am not dichromatic), just that I perceive it differently.
A test: Webexhibits – hover over “Protan” and “Deutan” (to the right of the dot pattern) and see what happens. For me there’s no change (only a slight change on the bud of the flower, but none in the dots).
