How to Use
Create beautiful, harmonious color palettes for your designs with this free online color palette generator.
- Pick a base color. Click any swatch to open the color picker, or type a hex value directly. This becomes the starting point for your palette.
- Choose a harmony mode. Select Complementary, Analogous, Triadic, or Split-Complementary to generate colors that work well together based on color theory principles.
- Lock and regenerate. Click the lock icon on any color you want to keep, then press the spacebar or click Generate to refresh the unlocked colors. Repeat until you find the perfect combination.
- Fine-tune with shades. Click a swatch to expand its shade and tint row — 9 variations from light to dark — so you can pick the exact tone for backgrounds, borders, or text.
- Export your palette. Copy individual colors in HEX, RGB, or HSL format, or export the entire palette as CSS custom properties or a Tailwind config snippet ready for your project.
The built-in WCAG contrast checker shows whether your color combinations meet accessibility standards (AA/AAA). All processing runs in your browser — no data leaves your device.

Frequently Asked Questions
- How do I create a color palette?
- Pick a base color in this color palette generator and select a harmony mode such as complementary, analogous, or triadic — the tool will instantly generate a balanced set of colors. You can lock any color you want to keep and regenerate the rest until the palette fits your project.
- What is color harmony?
- Color harmony refers to the principle that certain color combinations are visually pleasing because of their relationship on the color wheel. A color palette generator uses harmony rules like complementary (opposite hues), analogous (adjacent hues), and triadic (three evenly spaced hues) to produce combinations that work well together.
- What is the difference between complementary and analogous colors?
- Complementary colors sit directly opposite each other on the color wheel and create strong, high-contrast contrast, making them ideal for calls to action and highlights. Analogous colors are neighbors on the wheel and blend smoothly, which suits backgrounds and UI surfaces where you want a cohesive, low-tension look.
- How many colors should a palette have?
- Most design systems use 5–7 colors: a primary, a secondary, an accent, a neutral, and a few shades for backgrounds and text. This color palette generator produces palettes of up to 6 swatches, which covers the full range needed for a web or brand design project.
- How do I use a color palette for web design?
- Export your palette as CSS custom properties directly from this color palette generator and paste them into your stylesheet to apply consistent colors across your entire site. Assign roles to each color — primary actions, backgrounds, borders, text — and reference the variables throughout your components rather than hardcoding hex values.
