About Color Palette Generator

The color palette generator turns a single base color into a harmonious set of colors using classic color theory — the same relationships designers pull off the color wheel by hand. Every scheme is computed in the HSL color space, where hue is a 0–360° circle you can rotate to find colors that work well together. HSL is used here on purpose: unlike raw RGB, it separates a color's hue from its saturation and lightness, so rotating the hue keeps the palette's mood intact while the relationships between colors stay predictable.

Pick a base color with the swatch picker or by typing a HEX value, choose a scheme, and the palette updates instantly. Each color is shown in three formats — HEX, RGB, and HSL — so you can drop it straight into CSS, a design tool, or a brand style guide. Click any swatch to copy its HEX to your clipboard.

The six schemes cover the relationships you reach for most. Complementary rotates the hue 180° for the strongest, high-contrast pairing, which is why it works well for call-to-action accents. Analogous shifts ±30° for calm, cohesive combinations that feel natural, like colors you see next to each other in nature. Triadic spaces three colors 120° apart for a balanced, vibrant set. Tetradic uses four points at 90° for rich two-pair schemes with plenty of variety. Split-complementary softens a straight complement by taking the two hues 30° either side of it, keeping contrast without the tension of a direct pairing. Monochromatic keeps one hue while stepping the lightness, giving you a clean tonal scale for shadows, hover states, borders, and depth.

Use it for UI and web design, brand and logo colors, data-visualization palettes, illustration, and interior or fashion mood boards. A common workflow is to pick your brand color as the base, generate a complementary or triadic set for accents, then switch to monochromatic to build out the neutral tints and shades around it. When you apply colors to text and backgrounds, still check contrast against WCAG guidance — a harmonious palette is not automatically an accessible one.

Because everything runs on the color wheel with proper hue wrap-around (a hue of 350° plus 30° lands on 20°, not 380°) the results stay mathematically correct and predictable. Everything runs in your browser — no sign-up, no uploads, and your colors never leave your device.

Methodology & sources

Color schemes derived by rotating hue on the HSL color wheel (complementary +180°, triadic ±120°, analogous ±30°, etc.).

Frequently asked questions

What is the difference between complementary, analogous, and triadic colors?
They are positions on the color wheel. Complementary colors sit opposite each other (180° apart) for maximum contrast. Analogous colors sit next to each other (±30°) for a calm, harmonious look. Triadic colors are evenly spaced 120° apart for a balanced, vibrant set.
Can I use these colors in CSS or a design tool?
Yes. Every color is provided in HEX, RGB, and HSL. HEX and RGB drop directly into CSS or design apps like Figma, and HSL makes it easy to fine-tune saturation and lightness by hand.
Are my colors uploaded or saved anywhere?
No. The generator runs entirely in your browser using client-side JavaScript. Nothing is uploaded, stored, or sent to a server, and no account is required.
