The Color Palette Generator creates harmonious color schemes from a single base color using proven color theory principles. Choosing the right color combinations is one of the most challenging aspects of design, and mismatched colors can make even well-structured layouts look unprofessional. This tool generates five palette types — complementary, analogous, triadic, split-complementary, and monochromatic — giving you a complete set of coordinated colors with one click. Each swatch displays its HEX code and can be copied instantly. Pick a base color with the color picker, type a HEX value, or click Random for inspiration. All calculations run client-side in your browser, so no data is sent to any server.
About Color Palette Generator
Color harmony is the practice of combining colors that look pleasing together, based on their positions on the color wheel. This tool uses HSL (Hue, Saturation, Lightness) calculations to derive five types of palettes from your base color. Complementary colors sit opposite on the wheel and create high contrast. Analogous colors are neighbors and produce cohesive, low-contrast schemes. Triadic colors are evenly spaced at 120° intervals for vibrant, balanced designs. Split-complementary uses the two colors adjacent to the complement for a softer contrast. Monochromatic varies the lightness of a single hue for elegant, unified palettes. You get multiple ready-to-use colors without needing Figma, Photoshop, or any design software — just a browser and a base color.

Technical Details
Colors are computed in HSL (Hue, Saturation, Lightness). Complementary = hue + 180°. Analogous = hue ± 30°. Triadic = hue + 120° and + 240°. Split-complementary uses hues at + 150° and + 210°. Monochromatic keeps the same hue and varies lightness in even steps. All angles wrap around the 360° color wheel. The tool converts between HEX and HSL internally for accurate computation, and displays results as HEX codes for easy use in CSS. For precise RGB or HSL values of any generated color, use our Color Converter.
