Actually, Little Killer, are you sure you didn't mean black rather than white, when you shine coloured lights onto just the wall? Try it out.
On the back of a cathode-ray tube TV it would be white, and the lights' colours would be yellow, magenta and cyan. I was serious about attacking people with intense "light"/Electromagnetic waves. :O
Things are black because they don't reflect light. It's maybe something to do with their chemical composition. (I'm no chemist either :$). At this time, it's helpful to think of light as waves rather than discrete quanta (photons).
Dark matter as a phrase sounds like something out of science fiction or a video game, unless you mean it very literally.
