The complement of red is cyan. The complement of green is magenta. And the complement of blue is yellow. Show me that yellow is not blue's complement. Georgia guy 20:34, 14 October 2006 (UTC)Reply

Type "blue complementary color" into Google, and you will get several sites that make the claim. Plus I was an art major, if that has any merit. Orange is Blue's CC because they are across from each other on the color wheel, as are red & green, as are yellow & purple. Genuinearticle
