how many colors are on a color wheel
Color wheel Most color wheels are based on three primary colors, three secondary colors, and the six intermediates formed by mixing a primary with a secondary, known as tertiary colors, for a total of 12 main divisions; some add more intermediates, for 24 named colors. Other color wheels, however, are based on the four opponent colors, and may have four or eight main colors.
Color wheel The typical artists' paint or pigment color wheel includes the blue, red, and yellow primary colors. The corresponding secondary colors are green, orange, and violet or purple. The tertiary colors are green-yellow, yellow–orange, orange-red, red–violet, violet-blue and blue–green.
Color Electromagnetic radiation is characterized by its wavelength (or frequency) and its intensity. When the wavelength is within the visible spectrum (the range of wavelengths humans can perceive, approximately from 390 nm to 700 nm), it is known as "visible light".
Color wheel Analogous colors are colors next to each other on the wheel. For example, yellow and green. Monochromic colors are different shades of the same color. For example, light blue, indigo, and cyan blue. Complementary colors are colors across from each other on a color wheel. For example, blue and orange. Triadic colors are colors that are evenly across from each other, in a triangle over the color wheel. For example, the primary colors red, yellow, and blue are triadic colors.[16]
