Cold Colors are colors containing very little, if any, red or yellow.
Contrast Analogies. Apparent contrasts of secondary and tertiary colors which have constituent parts that are related. Thus compositions of citrine and plum are apparent contrasts, citrine being one of the three tertiary colors, russet, slate and citrine, and plum being composed of russet and slate, but in both citrine and plum there is red, yellow and blue; hence related. There can be no true contrasts excepting between primaries and secondaries.
Gray. Normal gray is black and white mixed, but quaternary colors are also called grays, or colors of the dull or neutral scale.
Harmony of Analogy is produced by using related colors.
Harmony of Contrast. The juxtaposition of a primary color, for example, with a secondary made of the other two primaries. Thus of the primaries red, yellow and blue, the contrasts would be red and green. Of the two colors thus forming contrast the one is said to be the Complementary of the other.
Hue. Applied to the predominating color in a composition.
Intense or Saturated Colors. Colors that are pure, having no tint or shade.
Neutral Colors. Applied to black, gray and quaternary colors.
Normal. Intense colors of the prism. Colors of the natural scale.
