I've gotta go, but this is rivetting.....
Do you mean as in red/blue, blue/green, etc. Or as in black/white skin colour?
I do believe it's emminently possible to be colour blind as far as skin colour goes. One ceases to be aware of what colour one's decor is, say in the lounge or the kitchen, and when pressed one has to conciously think.
And often the answer is well, this bit is such and such, but this bit is whatever.
You are a card. The sound works but not the picture, so it's not possible to know what the sound refers to. It might just be a syntheziser really.
And you mis-spelt bliind!
I know you made them up, I could tell the timbre in your comment. I twigged it straight away, but I thought I'd leave(s) you a message, hoping to get to the root of the problem.
Anyway, branching out to your other comment, "have you ever tried posting............":
I tend to stick with the tried and trusted method of envelopes, stamps and post boxes.
