How to Use
Choose a Base Color
Use the color picker to select your starting color, or upload an image to extract colors from it.
Select Harmony
Pick a harmony rule (mono, analogous, complementary, triadic, etc.) to auto-generate a matching palette.
Lock & Refine
Lock swatches you like, adjust individual colors, and regenerate until the palette feels right.
Check Contrast
Use the accessibility checker to verify WCAG contrast ratios between any two palette colors.
Export
Copy hex codes, download as CSS variables, JSON, or SVG — ready for your design system.
How to Calculate
The Color Palette Generator uses standard color theory algorithms to generate harmonies based on HSL color space. Base colors are rotated and adjusted in hue, saturation, and lightness to create visually appealing combinations. Image extraction uses pixel sampling and color quantization to identify dominant colors.
About the Color Palette Generator
The Color Palette Generator is a free online tool for creating beautiful color palettes. Start with a single color, upload an image for inspiration, or use harmony rules like monochromatic, analogous, complementary, split-complementary, triadic, and tetradic to build the perfect palette.
Palettes are generated from color math on your device; no image uploads or account needed. Lock a base hue, explore harmonious ramps, then copy hex codes straight into CSS or design tokens.
Export your palette as hex codes, CSS variables, JSON, or SVG swatches with a single click. Lock colors you love while exploring new combinations.
