Complementary RGB Color Pairs

[Mark Smith]

Stephen, in RGB, the values below are yellow and blue.

I have a distant memory that complementary colors are opposites on a  
color wheel - for each primary color, a mixture of the other two, so
if primary color = blue then complementary color = red + green = yellow.

Do you get the effect you want by simply subtracting each value from  
255?

Best,

Mark
