Nevermind, somehow I did not really read Kaels' post with enough concentration the first time...

No worries. It's very hard to explain what colorblindness actually looks like, because obviously, I can't know what non-colorblindness looks like.

I can tell you what it feels like though.. it doesn't feel like I'm really not seeing colors. It's more like, somewhere along the line, my brain can't decide if something is classified under "red" or "green". Now, I realise these are complimentary colors, and very different from eachother for other people...

Bright red and bright green aren't usually problematic. But any sort of in between color is confusing. Orange and green are practically the same to me, I wouldn't notice a greenish grey among neutral greys, and purple shades are very confusing too.

Nearly always, none of this is a problem. It only becomes a problem when the color specifically carries information (real world case: the three colors on sound cards, all vaguely yellowish/greenish/pink) that cannot be divined via other means such as position or shape. Or when someone asks "what color is this?". Or sometimes with painting/drawing/picking clothes.

Y'know, I have normal color vision, and I can't tell the difference between those blasted ports, either. I either have to drag a very bright light source behind my desk to sort it out, or just play with the plugs till it works. I don't understand why they can't have readable words next to them.

Agree on that, most of the ports are a dark-ish color with a blue component, so they are hard to tell apart on a "desktop" case that is actually standing below a desk.

As a color-blind person that crosses both the protanopia and deuternopia areas (elements #1 and #3 - although I never knew the official name for it - was alway severe red deficient) I can try and describe it pretty easily. Traffic red lights for those with my same type of color blindness are "red", while the normal color vision person sees "RED". The ability to see the red is so diminished in that spectrum that sometimes the lights almost seem non-existent. The other way to describe what I do see? Hehe - when I received my "final" diagnosis from the professor of opthamology at the local medical school here in Houston, his first comment to me after all the tests was - oh, so you see orange grass! He is absolutely right! I have been told there are no filters, shading, etc, that can ever help a color blind person see "normal" colors, and likewise there is nothing that a normal person can look through that would render things the way color-blind people truly see things. To this day its why I wear blue jeans and t-shirts mostly - - - its the only way I won't dress myself in something totally ridiculous. (My mom was always questioning my color choices - - and now we know why! LOL)

Oh - and the Ishihara color blindness test? Out of the standard 18 plates or so, I was lucky to get 4 correct.

I applaud Blizzard!
