Overheads

ok this puzzles me a bit.

You know the overheads old professors that don't know how to use powerpoint (or refuse to, whatever) uses. What would happen if you make, like, a gigantig overhead. And put a continious strip of color on a transparancy (ignore the fact that we're talking about color PIGMENTS here, so that my "theory" would hold anyway) but is color continious? Like, would you start to see "pixels" on the overhead if you had one sufficiently large? Is color countable, is it discrete or is it continious? With color, i'm more than likely refering to photons with different wavelengths.

I have another quote that I learnt from taking pictures in a picture vending machine the other day;
"Colour My World."
Now it's possible that the creator of this phrase did not realise it's signficance at the the time. But if we read this quote in relation to the argument in this thread, I have reason to believe that with my impeccable skills, I have found the answer that we all seek. This being, that colour is infact a Human Perception. That being said, I shall refer to the inferences in my previous argument, and therefore conclude that colour is infact, the epitome of human ignorance.
