And just to add $.002, the subtraction version works just fine if one
subtract the current color from the sum of both colors, so no need for an
array..

    (black + white) - black = white;
    (black + white) - white = black;

    (2000 + 1000) - 1000 = 2000
    (2000 + 1000) - 2000 = 1000

    (1 + 0) - 0 = 1
    (1 + 0) - 1 = 0

    (1 + 2) - 2 = 1
    (1 + 2) - 1 = 2

    ...

Well, I guess I better stop now...
