About the Color Palette Generator

Generate a coordinated color palette from a single base color. The tool derives complementary, analogous, triadic and shade variations using established color-wheel relationships, then outputs every swatch as HEX, RGB, HSL or a ready-to-paste block of CSS custom properties. Useful when you have one brand color and need a full set that works with it.

How to use the Color Palette Generator

  1. Pick a base color

    Enter a HEX value or use the picker. Every derived scheme updates from this single input.

  2. Choose a harmony scheme

    Switch between complementary, analogous, triadic and shade ramps to see different relationships to the base color.

  3. Copy in your preferred format

    Copy an individual swatch as HEX, RGB or HSL, or export the whole palette as CSS custom properties ready to paste into a stylesheet.

Frequently asked questions

What is a complementary color scheme?

Two colors sitting opposite each other on the color wheel. The contrast is strong, which makes complementary pairs effective for calls to action but harsh for large adjacent areas.

When should I use analogous colors instead?

Analogous schemes use neighbouring hues, producing a calmer, more cohesive look. They work well for backgrounds and surfaces where you want harmony rather than contrast.

Does this check accessibility contrast?

No. Harmony and contrast are separate concerns — a palette can be visually pleasing and still fail WCAG contrast requirements for text. Verify text and background pairs against a contrast checker before shipping.

What is the difference between HEX, RGB and HSL?

They describe the same colors in different notations. HSL is the most useful for editing by hand, because adjusting lightness or saturation is a single number change rather than a recalculation of three channels.
