I have a question, if a color is that color because it absorbs all the colors in the spectrum, except the one your seeing,
for example,
grass is green, grass absorbs, red, orange, yellow, blue, indigo, and violot...
but not green, it reflects green, so technically, wouldnt that make grass every color but green?
No is the short answer, it makes it green.
The only way to define the colour of an object is the colour of the light it reflects/emmits, defining colour in any other way is silly
Why don't we all have a masive debate about black being a colour or not. (which it isn't but i want to here other people opinions.

yes it is, in the same way that 0 is a number.
I say that all the color black you see around you is actually ultaviolet or "non color" light you are getting back to your eyes. So in a way we are actually "not" seeing the color black but instead we are seeing the lack of all non-black colors.
Here's another question:
I thought the primary colours are Red, Blue and Yellow?
Why do some people say it's Red Blue and Green? Green isn't primary! We can make it by mixing yellow and blue.
If you're mixing paint then the Primary colours are Red Yellow and Blue, If your mixing light the primary colours are Red Green and Blue.
If you mix red and green light you get yellow light
If you mix Blue and Yellow Paint you get green paint
The primary colours for mixing paint are completly different from the primary colours for mixing light.
Black can't be a colour, because we only see the colour(s) that are reflected off an object. If an object was black we wouldn't be able to see it, because no light is reflecting off it. Therefore the only thing that is black is a black hole.:p :p
I agree with you there that black is not a colur. Netither is white if we get down to it. They are both technically refered to as shades.
FOr you others, what is colour then? I mean the definition
There are two methods of splitting up colors
Addition method: Add a colours to black: Red green and blue: for light emitted or reflected by object
substract method: Substracting from white: Red yellow and blue, for object reflecting light
And the reds and blues are different from each other, i've seen this somewhere.
I'd say white is a color, a mixed color (R+G+B or R+Y+B).
