What is Analogous Colors?
Analogous colors are group of colors that are next to each other on the color wheel. For examples, Red, orange, red-orange, etc.
Analogous colors varies depending on the color wheel used. For example, by some definitions, it would be impossible to use Goethe's color wheel for similar colors, as they do not share a common color, such as blue-green. If you want to use the same colors as blue, blue-green, and green with Boutette's color wheel on the left, you won't be able to do so.
Analogous color schemes are often seen in natural settings, the human eye has been conditioned to give preference over color palettes that do not normally occur in nature. The color schemes are often used by designers to help portray some sort of expression that they want to emphasize in their designs. The analogous color scheme can be used to express themes such as luxury, romance, or nature, depending on the color set they choose.
