Isn't the opposite of red just cyan which is why people are confused if it's green or blue? I don't think the CMYK palette is necessary or practical when painting, but if you really want to be 'correct' about complimentaries and color mixing in a technical sense, the CMYK color wheel is what you want,

Correct me if I am wrong, I am still pretty new to color. Check out the CMYK wheel: http://www.ognigiorno.com/wp-content/uploads/2011/04/cmyk-color-wheel-lg.jpg
