Harmony rules

Analogous, complementary, triadic, split-complementary, tetradic, and monochromatic modes create mathematically beautiful palettes.

Lock & regenerate

Keep colors you love and randomize the rest. Fine-tune until the palette feels perfect.

Private & offline

All generation happens locally in your browser. Nothing is sent to a server.

How color harmonies work

Color harmonies are relationships between colors on the hue wheel. They have been studied for centuries and form the foundation of visual design. Analogous palettes feel calm and cohesive because the hues sit next to each other. Complementary palettes create strong contrast and visual impact because the colors are exact opposites. Triadic and tetradic schemes balance multiple hues for vibrant, complex designs.

This tool computes each harmony mathematically from a base color. You can lock any generated swatch to preserve it while adjusting the rest, giving you creative control without breaking the underlying harmony rule.

Exporting your palette

Once you have a palette you love, click Export Code to get it in the format your project needs. CSS custom properties work in any modern browser. SCSS variables are perfect for Sass-based workflows. JSON is great for design tokens or API payloads. The Tailwind config snippet drops directly into your tailwind.config.js.

Frequently asked questions

What is a color palette generator?

A color palette generator is a tool that creates cohesive sets of colors based on color theory rules. It helps designers and developers discover harmonious color combinations for websites, apps, branding, and artwork without guesswork.

How does the harmony mode work?

Each harmony mode applies a different color-theory rule: Analogous picks neighboring hues, Complementary selects opposite colors on the wheel, Triadic forms an equilateral triangle, Split-Complementary uses two adjacent opposites, Tetradic creates a rectangle, and Monochromatic varies only lightness and saturation.

Can I lock colors I like and regenerate the rest?

Yes. Click the lock icon on any color swatch to keep it fixed. When you press Regenerate or change the harmony, locked colors stay unchanged while the unlocked ones are recalculated.

How do I export a palette to CSS or Tailwind?

Click 'Export Code' and choose your format — CSS custom properties, SCSS variables, JSON, or a Tailwind config snippet. You can also copy all hex values at once with the 'Copy All' button.

Is this tool free to use?

Yes, it is completely free with no sign-up, no ads, and no usage limits.

Does this tool send my colors to a server?

No. All color generation, conversion, and export logic runs entirely in your browser. Your palettes are never transmitted, logged, or stored on any server.

What export formats are supported?

You can export as CSS variables, SCSS variables, JSON, or a Tailwind CSS config object. Each format is generated instantly and downloadable as a text file.

Can I use the generated palettes commercially?

Yes. The colors generated by this tool are yours to use in any personal or commercial project without attribution.

What is the difference between this and the Color Picker tool?

The Color Picker focuses on exploring a single color with conversions and contrast checking. The Color Palette Generator creates multi-color sets using harmony rules, perfect for building entire design systems.

How many colors can I generate at once?

You can generate between 3 and 10 colors per palette using the slider. The layout automatically adapts to fit the chosen number.
