An example of a complementary color scheme is ? A .Blue and Blue-green
B .Red, Orange and Yellow
C .Blue and Orange

I believe the answer is C. Blue and Orange

Explanation:

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black.[1][better source needed] When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors."
