I’d like to think that I have a reasonable grasp of the theory behind complementary colours. The problem is that the world doesn’t necessarily adhere to the principle and often seems quite happy to juxtapose any old clashing shades with nary a thought about the aesthetics of the matter.
Orange and blue are certainly complementary, and when the setting sun hits the underside of clouds, the vibrant orange glow it can produce sits very well against the still-blue sky. Crop out any earthbound distractions and you could get yourself a bit of abstract art.
Well, that’s my story and I’m sticking to it…
