Harmony is the analogy of contrary and similar elements of tone, of color, and of line, considered according to their dominants, and under the influence of a particular light, in gay, calm, or sad combinations . . . . Gaiety of tone is given by the luminous dominant; of color, by the warm dominant; of line, by lines above the horizontal."
