Guessing which colors go together wastes design time. This generator applies the classic color-wheel harmonies - the same hue relationships taught in color theory - so every palette is mathematically coordinated, not eyeballed. Click any swatch to copy its hex code, or copy the whole palette as ready-to-paste CSS custom properties. It is fully client-side: no account, no upload, no tracking of your brand colors.

What is a color palette generator?
A color palette generator builds a matching color scheme from one base color using color-wheel theory. Pick or type a hex color, choose a harmony like complementary, analogous, triadic or monochromatic, and it computes the coordinated colors instantly - each with a copyable hex code. Everything runs in your browser.
How to use
- 1Set your base color. Click the color well to pick visually, type a hex code like #6366f1, or hit Random for a fresh starting point.
- 2Choose a harmony. Switch between complementary, split-complementary, analogous, triadic, tetradic, monochromatic, shades and tints. The palette recomputes instantly.
- 3Copy the colors. Click any swatch to copy that hex code, or use the Copy button to grab the whole palette as CSS variables.
Who it's for
- Web designers starting a site from a single brand color: generate analogous or split-complementary companions for backgrounds, buttons and accents.
- Front-end developers who need a design-token starter: copy the palette as CSS variables and drop it straight into a stylesheet.
- Marketers and slide builders matching charts, social graphics or presentations to a logo color without a design tool.
- Illustrators and hobbyists exploring shades and tints of one hue to build depth, highlights and shadows in a piece.
FAQ
Is this color palette generator free?
Yes - 100% free with no sign-up, no watermarks and no limits. Generate and copy as many palettes as you like, for personal or commercial projects.
Is my color data uploaded anywhere?
No. The palette is computed entirely in your browser with plain JavaScript. Your brand colors, inputs and clicks are never sent to a server.
What is a complementary color?
The complementary color sits directly opposite your base on the color wheel - a 180-degree hue rotation. Complementary pairs like blue and orange give the strongest contrast, which makes them popular for call-to-action buttons against a brand background.
What is the difference between analogous and triadic palettes?
Analogous palettes use neighboring hues (within about 30 degrees of the base), so they feel calm and cohesive. Triadic palettes take three hues spaced 120 degrees apart, giving a vibrant, balanced scheme with more contrast between colors.
What are shades and tints?
Shades darken your base color by stepping its lightness toward black; tints lighten it toward white. Both keep the same hue and saturation, so they are ideal for hover states, borders and background layers of one brand color.
How many colors should a website palette have?
A common rule is 60-30-10: one dominant color for about 60% of the interface, a secondary for 30%, and an accent for 10%. Start from a 3-5 color harmony here, then add shades and tints of each for states and surfaces.
Why does the palette barely change for gray or black?
Grays, black and white have zero saturation, so they have no hue for the harmony rotations to act on - rotating nothing returns the same neutral. Build a neutral ladder with the lightness modes instead: tints for black or dark grays, shades for white or light grays, and monochromatic for mid grays.
