 Tertiary colors are the result of combining a primary color with one of its secondary color neighbors. For example, within the RGB color model, red (primary) and yellow (secondary) make orange (tertiary). This adds six more colors to a simple color wheel for a total of twelve.
 There are various methods of selecting different colors that result in a harmonious combination in design. One example that can use tertiary colors is called the split-complementary color scheme. This scheme starts with a base color, then pairs it with the two colors that are adjacent to its complement. The three colors provide strong visual contrast in a design, but are more subtle than using two complementary colors.
 Here are three colors created using the split-complement scheme:
