I am somewhat red-green colorblind (strong deutan), which doesn't exactly mean what it sounds like. I can see red and green, but I have a vast array of color confusion and a very limited vocabulary for colors. No need for words like fuchsia when you can't discriminate shades! A lot depends on how much light is available -- my color perception is a little better in bright light.
The
standard test has colored circles with numbers hidden in them. I can see the ones where the numbers are in one color and the background in another, but the others, I'm pretty hopeless at. The worst test for me, though, is the one that presents
an array of shades varying from one color to the next and you have to put them in the right order. These exhaust me. Entire blocks of them look identical to me.
When I was first told that I was colorblind, the doctor said I'd never be an electrician or a chemist. I got a PhD in chemistry -- not just to prove him wrong, though! I had a lot of trouble with titrations where color indicators are used to let you know you've neutralized the acid. The end-point was "the first hint of pink." By the time I saw anything, most of my classmates said it was pretty red!
My biggest problem: I don't understand the concept of colors clashing. Everything looks fine with everything else to me. So I tend to dress pretty conservatively. For the sake of others who might have to look at me.
My mother had a co-worker who was totally colorblind. Black & white stuff. He had to hang his matching outfits all on the same hanger or else he'd never get them straight.
