Random Colour Palette Generator

Click Generate for an instant harmonious 5-colour palette. Click any swatch to copy its hex code.

Generate colours that work together

A useful random palette should give you more than five unrelated colours. This generator starts with a random base hue, then builds the rest of the palette around a recognised colour harmony. Choose a harmony above and generate as many combinations as you need until one fits your project.

Click any colour to copy its HEX code, or use Copy All Hex to take the complete five-colour palette into your design app, website stylesheet or brand notes.

Choose a colour harmony

Different colour relationships create different moods. There is no single “best” palette: the right choice depends on how much contrast, variety and visual energy your design needs.

Analogous

Neighbouring hues create a smooth, cohesive palette with gentle contrast. A good choice for calm interfaces and editorial designs.

Complementary

Opposing areas of the colour wheel create stronger contrast. Use one side as the dominant colour and the other for accents or calls to action.

Triadic

Three colour families spaced around the wheel give a lively but balanced result. Useful when a project needs several distinct visual roles.

Split complementary

A base hue is paired with colours on either side of its opposite. It keeps useful contrast while feeling less severe than a direct complementary scheme.

Monochromatic

One hue is varied through lighter and darker values. This is an easy way to create a controlled, consistent system for a single-colour identity.

How to use a generated palette

Once you find a combination you like, give the colours jobs instead of using every swatch equally. A simple starting point is the 60–30–10 rule: use roughly 60% of the dominant colour, 30% for a secondary colour and 10% for a contrasting accent. The remaining colours can support backgrounds, borders, illustrations or interaction states.

For websites: do not assume that colours which look good together are automatically readable together. Before using a generated colour for text, buttons or interface controls, check the foreground and background pair with the colour contrast checker.

Random palettes work well for early-stage exploration: website concepts, logo and brand directions, presentation themes, illustrations, social graphics and moodboards. When a random combination gives you a promising starting point, refine it around the needs of the project rather than treating all five generated values as fixed.

Build the palette into a complete colour system

A generated palette is often the beginning rather than the end. You can use other ColorSchemePro tools to develop or validate it:

Random colour palette FAQs

Are these colours completely random?

The starting hue is random, but the remaining colours are generated using the harmony you select. This keeps a relationship between the colours instead of producing five unrelated HEX values.

Which harmony should I choose?

Try analogous or monochromatic for a more unified look. Complementary schemes create stronger contrast, while triadic and split-complementary palettes introduce more colour variety.

Can I use the generated HEX colours in CSS?

Yes. Click a swatch to copy its HEX value, or copy all five values and use them in CSS variables, design software or any application that accepts hexadecimal colours.

How many times can I generate a palette?

There is no limit. The generator runs in your browser and you can create new palettes as often as you like.
