Runge’s color orb and color patterns were invented in history
The opposite color to blue is orange, and the most opposite to yellow is purple. ” Harrris’s wheel of dynamics had a great influence on painters, including Joseph Turner (1775 – 1851) – British artist with paintings predicting the birth of French Impressionist painting in the 19th century. Harris’s dither wheel also initiated the introduction of a series of dither wheels by other authors such as James Sowerby in 1809, George Field in 1817 and Charles Hayter in 1826.
Opponents of theory Newton’s dithering uses Harris’s dither wheel as proof that the colors in fact do not obey the dither law of light.
Hemisphere colors of Chevreul
Inheriting the color sphere of Runge, in 1839 French chemist Michel Eugène Chevreul (1786 – 1889) proposed a color hemisphere model. He divided the equator of the sphere into 6 equal parts for the 3 primary colors red, yellow, blue and 3 secondary colors orange, green, purple. Each color section is divided into 12 colors, a total of 72 colors are arranged around the equator. The dark brightness of each color is determined by the black factor (nero factor): the darkest at the hemisphere surface, the whiter the center of the heart becomes. The axis perpendicular to the equator plane (ie the axis from the north pole to the center of the sphere) has only two black and white colors that change from black at the top to white at the center.
Chevreul also carefully studied the effect that occurs when colors are placed side by side, about color contrast, about the appearance of light streaks at the boundary between light and dark colors (Chevreul illusion). Chevreul’s work on colors has had a great influence on Impressionist, New Impressionist and Post-Impressionist painters.
