OT: Question about RGB color method

[Paul McGuire]

Ah, the Wikipedia article for "Primary Colors" is much better at
explaining this than the one for "RGB Color".  For instance, in the
Tempra-paint-compatible subtractive system, you probably recall mixing
red, yellow, and blue, and getting black, or at least a dark muddy
brown.  Conversely, in the additive system of RGB, mixing red, green,
and blue, gives you... white!  You've combined all the light there is,
you should get the lightest color of them all.
