I decided to take a walk around the colour wheel with this model. The client sent a wonderful picture of a kingfisher in mid flight, with a plumage that ran the course from purple to yellow. It is easy to confuse the eye when using multiple colours on a piece, following the example found in nature gave a reassuring skeleton to the paint job that I could build on.
