Analogous

An analogous color scheme is made up of any three colors that are next to each other on the color wheel and share a common hue. For example, yellow-green, yellow and yellow-orange all contain yellow. In an analogous color scheme it's common for one of the three colors to predominate. Notice that Wembly Fraggle is mostly yellow-green, but the yellow and yellow-orange in his hair help create a harmonious color scheme.
