i saw mention of this on another thread so i thought i'd rave on about it for the pleasure of people with nothing better to do than listen to me.

black is the absense of all light, hence color. but black is a mixture of all colours aswell(well, more like brown but we get to that later)
white is all colors put together with an equal amount of each color.. yet white is also no color.

the thing is, there is additive(RGB) and subtractive(CMYK) colouring.. i forget why that is but theres a good explanation on it that relates to frequencies of light.. your printer at home, when it prints green, mixes the cyan and yellow ink together to make green.. the monitor you're looking at fires only the green cathode ray out of the possible blue,red and green guns.

the printer is using subtractive coloring, and because of that it needs cyan,yellow and magenta to make all possible colors.. also the printer needs black because all colours mixed together only make a very dark brown. black is the 'K' in cmyk.

the monitor is using additive coloring and to make white, it fires all guns at full strength to make a white dot on the screen. firing the red gun and green gun together actually creates yellow because of the combination of the two frequencies yadayadayada.

experiment with additive color- open up mspaint and create a custom color, mixing different levels of red, green, and blue.

Ever considered becoming a auto spray painter/colour matcher.
Note correct spelling of colour not the american version.

That stuff is pretty interesting i reckon, we were learning about colours of light and stuff in physics. If it wasn't school holidays and I was a lot less tired i might even try to contribute something constructive to this thread but ah well at the moment blowing stuff up with a giant magnifying glass seems just that much more important.

I feel like I'm in Physics class again!

Let me try...

How about taking a single colour and turning it into many varied and splendid colours? No, I don't mean something lame like splitting white light into its components, but something more along the lines of...

Imbibe a lot of liquid amber and soon you shall experience the Technicolour Yawn�.

For the literally challenged, I present this flowchart:
