About this tool
Color Palette Generator is a free online color tool. Generate harmonious color palettes. Handy for designers, artists, and developers. It runs entirely in your browser — no download or sign-up needed.
Upload an image, and the tool extracts the main colors from it to generate a color palette. You can also enter keywords (such as "ocean","sunset","forest") to generate theme colors. Support multiple color matching rules: complementary color, similar color, three-role color matching, quadruple color matching, and monochrome color matching.
Color matching principle: Based on the color wheel relationship. Complementary colors refer to the colors opposite the color wheel (strong contrast), similar colors are adjacent colors (harmonious unity), and triangular color matching refers to the three vertices of a regular triangle (balanced and rich).
The palette can be output to ASE (Adobe), CSS variables, JNON, PNG images and other formats. It is suitable for designers to quickly find inspiration, developers to unify project color matching, or artistic creation reference. You can save frequently used color palettes to the cloud.
The color scheme generator automatically generates a coordinated color palette from pictures or keywords, supporting multiple color rules and output formats.
