I think describing color to anyone would be like speaking gibberish.  Honestly describing any mental state or perception just totally breaks down, in my opinion.  But I'm one of those crazy clowns who still reads Wittgenstein.

Whatever that is. Also, Strop, I'mma shoot your ROFFLECOPTER wif my IndestructoCopter. :P

I think words come with sensations for blind people. I mean, if your other senses are how you "view" the world, then maybe it isn't illogical to think that with a better perspective on blindness, a seeing person could describe green by using a series of words that have a particular feeling to them, or sentiment, or texture. The only problem is, we the seeing have no concept of word texture (not in the same way the blind do, unless you have synaesthesia :P) Oh, wait, yeah. Just get synaesthetics to describe green to the blind; some of them experience color through other senses anyway.

One of my classmates is a pianist with synaesthesia, and he says certain notes are connected to certain visions, be they color or image or some combination. Pretty cool.

Can someone please explain why we would be explaining colour to a blind person in the first place? If they were born blind, then they wouldn't even know that colour existed unless told about it, and I doubt they would ask since they would never see it. If they were blinded later in their life, most likely they had working eyes before they went blind and saw the colourful world around them. :O
For describing colour though, I don't know all these technical words everyone's using, but i'd probably describe the colours to what they would normally relate to, red would be a warm colour, or angry, blue would be cool and such, and so on. No doubt they'd get a good idea of what it would generally 'look' like, or it's presence would have an effect of to someone like in a painting, not general use.

wow, reading these posts hurts my head. i find it very hard to attempt to think logically :D

any way, my description of color... well, its not really a feeling, i mean, it cant be... well, colors do represent feelings to a point i suppose, but if u dont know colors exist, then how can they stand for anything? but, how can colors not exist though? i mean, what color does a blind person see? i mean, they cant see, but, that feeling has to exist somehow, doesnt it? i mean, can u imagine there being no such thing as sight?

oops i didnt mean feeling but that sense

Well, colour is made through our brain and eye's cooperation, also, you can imagine colour in your head, now you know what colour looks like, so you automatically use them, but what if you never saw colour before? The colours we see everyday are 'mandatory' for us, therefore, when someone who has never seen anything like it before, couldn't they think about it? Even perhaps imagine new colours not see-able(as they've never been exposed to the spectrum we see). I'm not saying it's possible, but then again, I'm not blind, I've seen the world, and I don't study and 'ologies' that circulate around the human neurological system and such.
