The scales of an infinite fractal spiral exhibit varying concentrations of blue, white, and brown. Structure is built up as the rendering process periodically layers color onto eac h spiral arm. Color mixing occurs because the number of arms (37) is not divisible by the number of input colors (3). Scale coloration of every third arm in the spiral slowly changes before returning to its starting state after three revolutions. Distinct scales that arise are reminiscent of rock spall, a common form of weathering that causes flakes of rock to break free from the surface of a larger body. Show more
