Isaac Newton, seven-part color wheel of the pure spectral colors (around 1700)

Colors, in contrast to dyes, are those sensory qualities that are conveyed to man through the eye, insofar as he thereby disregards the form and structure of what he sees[1] and are associated with very specific emotional color sensations. According to Goethe, colors are "deeds of light, deeds and sufferings."[2] A distinction can be made between light colors, which emanate directly from a self-luminous light source,[3][4] and body colors, which are produced by transillumination or reflection on material objects. In contrast to chromatic colors, white, black, and all intermediate neutral grays without a color cast are called achromatic. What has no colors is colorless. Colors can be characterized in the HSV color space by hue, saturation and value.

The pure spectral colors, which are also called primary colors or primary colors, have the greatest color saturation (chromaticity). Secondary colors are mixtures of two, tertiary colors of three primary colors. Depending on the mixing ratio, the most diverse (ideally all) color tones can be achieved. Glaring, screaming colors with particularly high luminosity and color saturation are also called neon colors. Luminous paints, some of which also glow or afterglow in the dark, emit more light in the visible range than they absorb from the outside.

Warm and cool colors

Red to yellow and brown hues are mostly experienced as pleasant active warm colors. Green and blue to violet hues, on the other hand, are usually experienced as passive cold colors, as Goethe also described in detail in his Theory of Colours under the "sensual-moral effect of color". Warm colors also objectively lead to a measurable increase in blood pressure and respiratory and pulse rates in test subjects, while these decrease with cold colors.[5]

  1. According to the definition in DIN 5033, color is "the visual perception of a part of the visual field that appears structureless to the human eye, by which this part alone can be distinguished from an adjacent district that is seen at the same time and is also structureless, when observed with the unaided eye.
