Free browser-based color palette generator. Create harmonious color schemes — complementary, triadic, analogous, monochromatic, and more. No sign-up required.
Click the swatch to open the color picker, or type a HEX value. Hit Random for inspiration.
Select a color relationship — Complementary, Triadic, Analogous, Monochromatic, Shades, and more.
Click any swatch to copy its value, or export the whole palette as CSS variables or JSON.
A free browser-based color palette generator that creates harmonious color schemes from a single base color. Choose from 8 harmony modes, adjust palette size, copy any swatch in HEX/RGB/HSL, and export the full palette as CSS variables or JSON — no sign-up required.
Complementary colors sit directly opposite each other on the color wheel (180° apart). This creates high contrast and visual tension — great for call-to-action buttons or bold designs. A complementary palette pairs the base color with its direct opposite plus supporting neutrals.
Shades are created by mixing black into a color, making it progressively darker. Tints are created by mixing white in, making it lighter. Both modes give you a range of the same hue from dark to light — ideal for building monochromatic UI themes or gradient systems.
Click the ⬇ CSS button to generate a CSS snippet with each color defined as a custom property (e.g. --color-1: #f97316;). Copy it and paste it into your :root block. Rename the variables to something meaningful like --brand-primary.
Analogous colors are adjacent on the color wheel — typically spanning 30° on each side of the base hue. They are naturally harmonious and pleasing to the eye. Analogous palettes are common in nature-inspired designs, photography, and calm UIs.
No. All processing happens client-side in your browser. Saved palettes are stored only in your browser's localStorage — nothing is sent to any server. Clear your browser data or use the Clear button to remove saved palettes.
The JSON export gives you an array of color objects, each containing the color's index, HEX value, RGB components, and HSL values. This is useful for importing palettes into design tools, config files, or custom theming systems.
A color palette generator creates a set of harmonious colors from a single base color using rules from color theory. Instead of manually guessing which colors work together, the generator applies mathematical relationships on the color wheel to produce combinations that are visually balanced and aesthetically pleasing.
This free online tool supports eight harmony modes and lets you export results as CSS variables or JSON — ready to drop straight into your project.
Each mode uses a different geometric relationship on the HSL color wheel:
Modern design systems define colors as CSS custom properties in a :root block. This makes it easy to swap themes, ensure consistency, and update brand colors from one place. The CSS export from this tool gives you a ready-to-use snippet:
:root { ... } block into your main stylesheet--primary, --secondary, --accentvar(--primary)Color theory provides rules, but good design requires judgment. A few practical tips: use the 60-30-10 rule — 60% dominant color, 30% secondary, 10% accent. Always check contrast ratios against your background to meet WCAG AA (4.5:1 for text). Monochromatic and analogous palettes are safest for beginners; triadic and tetradic require more balancing but yield more dynamic results.
