A color wheel is a collection of colors that are arranged in accordance with their chromatic relationship. The color wheel is also called a color circle, and consists of primary, secondary and tertiary colors. Most color wheels consist of 12 main divisions and include three each of primary and secondary colors, as well as six tertiary colors. Tertiary colors are the colors that are created from a mixture of primary and secondary colors. Other color wheels typically have either four or eight main colors.
Primary colors are colors that are in their most basic form. These colors do not have the ability to be created by mixing other colors, and include blue, red and yellow.
Secondary colors are the colors that are formed when mixing two primary colors together. The secondary colors include orange, violet and green. Orange is achieved by mixing yellow and red; violet is achieved by mixing blue and red; and green is achieved by mixing yellow and blue.
Tertiary colors are the six colors that come from mixing primary and secondary colors. These colors include blue-green, blue-violet, yellow-green, yellow-orange, red-violet and red-orange.
Complementary colors are those that are positioned on the direct opposite side of the color wheel from each other. For instance, red and green are complementary colors.
Analogous colors are the colors that are close to one another on the color wheel, and consist of primary, secondary and tertiary colors.
The Color Wheel
The color wheel is able to be divided into visually passive or active ranges. When the active colors are beside the passive hues, they seem to advance. Likewise, the passive colors seem to recede when beside the active colors.
The relationship between colors is displayed as a color triangle or a color wheel.
The Painter’s Color Triangle
The colors that are involved in a painter’s color triangle are the colors that are learned as children. The primary colors are the same as the color wheel.
The Printer’s Color Triangle
The primary colors in a printer’s color triangle are yellow, cyan and magenta. These colors are used during the printing process.
