| 释义 |
Color wheelRYB (red–yellow–blue) make up the primary color triad in a standard artist's color wheel. The secondary colors purple–orange–green (sometimes called violet–orange–green) make up another triad. Triads are formed by three equidistant colors on a particular color wheel. Other common color wheels represent the light model (RGB) and the print model (CMYK). HistoryThe first known instance of the RYB triad can be found in the work of Franciscus Aguilonius (1567–1617), although he did not arrange the colors in a wheel.[2] The RYB model was used for printing, by Jacob Christoph Le Blon, c. 1721–1725.[3] In the 18th century, the RYB primary colors became the foundation of theories of color vision, as the fundamental sensory qualities that are blended in the perception of all physical colors and equally in the physical mixture of pigments or dyes. These theories were enhanced by 18th-century investigations of a variety of purely psychological color effects, in particular the contrast between "complementary" or opposing hues that are produced by color afterimages and in the contrasting shadows in colored light. These ideas and many personal color observations were summarized in two founding documents in color theory: the Theory of Colors (1810) by the German poet and government minister Johann Wolfgang von Goethe,[4] and The Law of Simultaneous Color Contrast (1839) by the French industrial chemist Michel-Eugène Chevreul.[5] The cyan, magenta, and yellow primary colors associated with CMYK printing are sometimes known as "process blue", "process red", and "process yellow".[6][7] See also
