This incompatibility between classical color theory and reality struck Goethe in the late eighteenth century. Intensely aware of the phenomenal reality of colored shadows and colored afterimages, of the effects of contiguity and illumination on the appearance of colors, of colored and other visual illusions, he felt that these must be the basis of a color theory and declared as his credo, “Optical illusion is optical truth!” Goethe was centrally concerned with the way we actually see colors and light, the ways in which we create worlds, and illusions, in color. This, he felt, was not explicable by Newton’s physics, but only by some as-yet unknown rules of the brain. He was saying, in effect, “Visual illusion is neurological truth.”
