24 colors' analogous colors

Quick answer：

Analogous colors refer to colors that are next to each other on the color wheel. For 24 colors, each color would have at least two analogous colors. To provide a comprehensive list would require knowledge of the specific color palette in question. If the palette is not specified, it's not possible to give a precise answer. The concept of analogous colors is fundamental in color theory and is used in design, art, and color psychology.
