Free Color Palette Generator - Harmonious Colour Schemes

Generate beautiful colour palettes with random, monochromatic, complementary, triadic and analogous schemes. Copy HEX, RGB or CSS.

What Is Color Palette Generator?

A colour palette generator creates harmonious colour combinations based on colour theory principles. Starting from a base colour, it generates complementary, analogous, triadic, split-complementary and monochromatic palettes — each following mathematical relationships on the colour wheel that produce visually pleasing combinations.

Colour palette design is one of the most impactful aspects of visual design. The right palette creates mood, guides attention and builds brand identity. However, choosing colours that work well together is difficult without understanding colour theory. This tool applies the theory automatically, producing palettes that are guaranteed to be harmonious.

How to Use This Tool

  1. Enter a base colour in HEX, RGB or use the colour picker.
  2. Select a harmony type: complementary, analogous, triadic, split-complementary or monochromatic.
  3. View the generated palette with colour swatches and codes.
  4. Click any colour to copy its HEX, RGB or HSL value.
  5. Export the palette for use in your design project.

Tips & Best Practices

  • Start with your brand or key colour and build the palette around it.
  • Analogous palettes (adjacent colours on the wheel) feel calm and harmonious.
  • Complementary palettes (opposite colours) create high contrast and visual energy.
  • Use the 60-30-10 rule: 60% dominant colour, 30% secondary, 10% accent.

Common Use Cases

  • Creating colour schemes for websites, apps and graphic design projects.
  • Building brand colour palettes with harmonious relationships.
  • Finding complementary or accent colours for an existing design.
  • Exploring colour theory through interactive experimentation.
