Analogous colors on a 24-color wheel refer to a range of colors that are adjacent to each other on the wheel. These colors are closely related and provide a harmonious and balanced look when paired together. For example, a warm analogous color scheme might include red, orange, and yellow, while a cool analogous scheme could combine blue, purple, and green. The key to effective analogous color pairing is to choose colors that are close in value and hue to create a cohesive and visually appealing composition.
