Why Use This Tool
Creating visually harmonious color palettes is a core skill in UI/UX design. This tool automates color theory calculations to generate analogous, complementary, triadic, split-complementary, and tetradic schemes from any base color — saving time and ensuring aesthetic consistency.
Each scheme follows established color theory principles: analogous colors are adjacent on the color wheel for harmony, complementary colors create contrast, triadic schemes offer balance, and tetradic schemes provide rich, complex palettes.
Frequently Asked Questions
The tool accepts HEX (#ff5733), RGB (rgb(255,87,51)), and HSL (hsl(14,100%,60%)) formats. All output swatches display HEX codes for easy copying into CSS and design tools.
Colors are converted to HSL (Hue, Saturation, Lightness) for calculation. Hue angles are rotated on the color wheel: analogous rotates 30 degrees each way, complementary adds 180 degrees, triadic adds 120 degrees, split-complementary uses 150 and 210 degrees, and tetradic uses 90, 180, and 270 degrees.
Yes. Click any swatch to copy its HEX code. All HEX values are valid CSS color values. You can also use the RGB or HSL values shown for the base color directly in your stylesheets.
