What is Analogous colors?

Analogous colors are groups of three colors that are next to each other on the color wheel, and a tertiary. Red, orange, and red-orange are examples.

The term analogous refers to having analogy, or corresponding to something in particular. An analogous color scheme creates a rich, monochromatic look. It is best used with either warm or cool colors, creating a look that has a certain temperature as well as proper color harmony. While this is true, the scheme also lacks contrast and is less vibrant than complementary schemes.
