tertiary colors
Tertiary colors are the resulting color formed when an equal amount of a primary and a secondary color are mixed. The primary and secondary color must be beside each other on the color wheel. For example, a mixture of 50-percent red and 50-percent magenta would result in the tertiary color of orange.
