What is a Color Palette Generator?
A Color Palette Generator helps you build cohesive color sets for UI design, branding, illustrations, and content. Instead of picking random colors one by one, you can generate matching swatches based on harmony rules and quickly export them for real projects.
How to use this tool
- Pick a harmony mode to control how colors relate to each other
- Choose a seed color when using non-random harmony modes
- Click Generate to create a fresh set while keeping locked swatches unchanged
- Lock swatches you like and regenerate until the palette fits your style
- Copy or export as HEX/RGB/HSL, CSS variables, or JSON
Harmony modes explained
- Random: Creates fully random swatches for quick inspiration.
- Complementary: Uses opposite hues on the color wheel for strong contrast.
- Triadic: Uses three evenly spaced hues for vibrant balanced palettes.
- Analogous: Uses neighboring hues for smooth, harmonious looks.
- Split-Complementary: Pairs one base hue with two near-opposites for flexible contrast.
- Tetradic: Builds a four-hue scheme for rich, varied combinations.
- Monochromatic: Keeps one hue and varies lightness/saturation for consistent styling.
Tips for better palettes
- Start with your brand or accent color as the seed, then lock your favorite swatches first.
- Check text contrast before using colors in production interfaces.
- Use HSL export when you want easier fine-tuning in CSS.
- Export JSON to reuse your palette in design tokens or app config files.
