analogy colors and analogous colors

Quick answer：

Analogous colors are hues that are next to each other on the color wheel. They are similar in value and chroma, and are often used in color schemes to create a harmonious and balanced look. Analogy colors, on the other hand, are colors that are similar in nature or characteristics, but not necessarily next to each other on the color wheel. This term is less commonly used and can refer to colors that share certain traits, such as warmth or coolness.
