Quick answer: Pick a base colour. Generate palettes based on colour theory rules, copy HEX/RGB/HSL values for design work.

Starting a palette from scratch

Pick one colour that represents the brand's mood β€” warm for friendly, cool for trustworthy, saturated for energetic. Generate a harmony around it, then neutralise: most palettes need a grey ramp plus one or two accent colours, not six competing hues.

60-30-10 rule

Use the dominant colour on 60% of a design, a secondary on 30%, and an accent on 10%. Works for interiors, slide decks and web interfaces alike.

Frequently Asked Questions

What's the difference between the harmony types?

Monochrome: shades of one hue. Analogous: neighbouring hues on the wheel. Complementary: opposite hues. Triadic: three evenly spaced. Tetradic: four in a rectangle. Each creates a different mood.

How many colours should a palette have?

For a UI, 5–7 is typical: 1 primary, 1 accent, 2–3 neutrals, plus success/warning/error semantic colours. Fewer forces clearer hierarchy; more invites inconsistency.

Are the palettes accessibility-safe?

The generator outputs palettes, not accessibility guarantees. Always run foreground/background pairs through a WCAG contrast checker before committing β€” 4.5:1 for text, 3:1 for large text.

Can I export for Figma or Tailwind?

Yes. Copy as hex list for Figma styles, or as a Tailwind-ready config object with keys 50–900 for a full ramp.
