Nature's complement

The Saturday Self Challenge this week is: "Complementary Colours".

Complementary colours are pairs of colours which, when placed next to each other, they create the strongest contrast for those two colors. Complementary colours may also be called "opposite colours."

I have chosen to use the traditional colour wheel model which dates back to the 18th century and is still used by many artists today. This model designates red, yellow and blue as primary colors with the primary–secondary complementary pairs of red–green, blue-orange, and yellow–purple.

Nature hasn't read the rules but manages to set the standard.
