How to use

How to build a harmonious color palette from one base color

  1. 1 Start with a brand color, mood-board swatch, or random shade using the color picker or HEX input.
  2. 2 Pick a harmony rule such as complementary, analogous, triadic, split-complementary, tetradic, or monochromatic to shape the palette.
  3. 3 Review the five generated swatches and use the built-in HEX and RGB values to compare how the palette will work in design and CSS.
  4. 4 Copy individual colors when you need one accent tone, or export the entire palette as CSS custom properties for a project.
  5. 5 Use Randomize to discover fresh starting points until you find a combination that fits your UI, illustration, brand, or presentation.

A color palette generator saves time when you need more than one attractive color but do not want to guess at hue relationships manually. By starting from a base color and applying well-known harmony rules, the tool helps designers, developers, and marketers build palettes that feel intentional instead of arbitrary. This is helpful for user interfaces, charts, social graphics, dashboards, and any project where consistency matters.

Export options make the palette useful beyond inspiration. You can copy a single swatch, grab the full list of HEX values, or generate CSS custom properties for immediate use in a stylesheet or design system. Because everything happens in the browser, it is easy to iterate quickly until you land on a palette that balances contrast, cohesion, and brand fit.
