Complementary RGB Color Pairs

[Stephen Barncard]

I know there's a simple formula for this, but my brain hurts tonight.

I would like to calculate the complementary color from an inputted color trio.

For instance I know that these two sets of two colors are complementary.

0,128,128
128,0,0

255,0,0
0,255,255

represented in binary, they look like this


00000000,10000000,10000000
10000000,00000000,00000000

11111111,00000000,00000000
00000000,11111111,11111111


YELLOW and GREEN look like this

255,255,0
0,0,255

11111111,11111111,00000000	yellow
00000000,00000000,11111111	green


some of these look like simple inversion but I don't think it's quite 
that simple.

I'm sure someone has worked this out...
thanks
