Where are the Black 2004's???
I think you slept through class - white light has all the colors of the visible spectrum. Now about spelling class......
Some general background facts on colors may now be appropriate. It is widely known that ordinary "white" light consists of an even mixture of all colors, while ordinary "black" objects absorb all those colors. Any other thing, if it possesses color, has it because it always absorbs at least one of the different colors of white light. Sometimes an object absorbs several different colors, and not uncommonly it may absorb all but one. Furthermore, an object may only partially absorb one or several colors. A grey object reflects all colors at equal intensity -- all the colors in an impinging white light are partially absorbed, equally!
