A paint color mixing chart, or a paint color wheel, is comprised of 12 pure colors which are organized in a way that shows how they were derived. This color mixing chart offers a great way to learn how different paint colors are created and how they relate to one another.
Red, blue and yellow are called primary colors. Unlike secondary, tertiary and quaternary colors, primary paint colors cannot be "made" by mixing. These 3 colors give origin to the rest of the colors you see on the color wheel.
There are three secondary paint colors on a color wheel. These are created when two primary colors are combined together in equal amounts. For example, violet is a result of red and blue. The secondary colors are positioned right between the three primary colors on the paint color mixing chart.
Intermediate paint colors are the remaining six colors found on a typical color wheel. They are produced by mixing a primary color with an adjacent secondary color. For instance, yellow and orange produce yellow-orange color. The intermediate colors are placed between the primary and secondary colors.
The third level of mixing paint colors produces tertiary colors. They are formed when two secondary colors are combined. For instance, orange and violet result in brick violet. Tertiary colors are usually not displayed on a basic paint color mixing chart, to keep things simple.
There is a fourth level of mixing paint colors, which is also not shown on a regular color wheel. When two tertiary colors are mixed, quaternary paint colors are formed. These colors are the most complex and add depth and sophistication to paint color schemes.
