Color Palette Generator
Harmonious 5-color palettes from any base color
🔒 100% free · no signup · files never leave your device
Pick colors at random and a design looks amateur within seconds; pick them with a system and even a spreadsheet looks intentional. Color harmony is that system: hues chosen at fixed angles on the color wheel. Analogous palettes (neighbors on the wheel) feel calm and cohesive, complementary pairs create deliberate tension, triadic sets stay vivid while naturally balanced, and monochromatic scales give you five guaranteed-to-match shades of one hue. Designers have used these relationships for centuries because they reliably work.
This color palette generator turns one base color into a five-color harmonious palette instantly. Choose your starting hex, flip between analogous, complementary, triadic, split-complementary and monochromatic harmonies, or roll a fully random palette until something clicks. Every swatch copies its hex on click, and a ready-made CSS variables block exports the whole palette in one action. It's the fastest way to go from 'brand color roughly blue-ish' to a working five-token design system — all client-side, no account, no downloads.
Why use Color Palette Generator
Starting a brand or side project
You have one brand color from the logo; harmonies generate the supporting cast — backgrounds, accents, hover states — that actually match.
Designing data visualizations
Multi-series charts need distinct-but-related colors; analogous and triadic palettes give five distinguishable, non-clashing series colors.
Building a dark-mode variant
Monochromatic palettes deliver the lightness ladder for surfaces — pick one hue, emit five shades, assign to bg/card/border.
Choosing accessible UI colors
Generate candidates fast, then check text/background pairs for contrast compliance before committing to a design.
Pro tips
- The 60-30-10 rule keeps palettes usable: one dominant color (60%), one supporting (30%), one accent (10%) — a generated palette is your menu, not a mandate to use all five equally.
- Always test palettes against real content with real text; swatches that look balanced in isolation can fail contrast the moment they're behind type.
- Use lightness variations of one hue for UI surfaces (monochromatic harmony) and reserve bold complementary colors for actions and alerts.
- Lock in the base color from actual brand assets first — palette math can't rescue a base color that clashes with the logo.

Frequently Asked Questions
What is a color harmony?▾
Colors picked by fixed angular relationships on the color wheel. Analogous colors sit side-by-side (calm), complementary sit opposite (high contrast), triadic are 120° apart (balanced yet vivid).
Can I use these palettes commercially?▾
Yes — colors can't be copyrighted. Generate and use them in any project.
