Analogous colors are colors that are next to each other on a color wheel, usually the standard 12-color chart. These color combinations usually have a primary or secondary color with one or more tertiary colors supporting them.
Primary (red, yellow or blue) colors or secondary colors (green, orange and purple) tend to be the major color in an analogous color scheme. The colors next to them are tertiary, made by mixing primary and secondary colors. For example, red-orange is a tertiary color, a mix of one primary and one secondary color. Red and red-orange are analogous colors, as are blue and blue-green. Because these color schemes are often found in nature, they are associated with a natural and serene aesthetic.
