Complementary Colours


I’m not sure if they are exactly complementary colours, but they look close to me. It’s curious that nature recognises this element of design, almost certainly used to attract the right kind of insects. I read somewhere that bees favourite colours are yellow and blue, so that may explain it. It does not, of course, explain how someone determined that bees favourite colours were yellow and blue – presumably there was a questionnaire the bees were asked to fill in.
