Quick answer
A color palette generator creates related swatches from one base color.
Best inputs

Brand colors

Start with a product, brand, or accent HEX value.

UI experiments

Generate token drafts before checking contrast and applying components.

Example, assumptions, and limitations
Palettes are design starters, not final accessibility approvals.

Example

A green base color can produce lighter tints, darker shades, and a complement swatch.

Assumption

The entered HEX value is the base color for a token draft.

Limitation

The tool does not verify brand fit, contrast compliance, color blindness safety, or final theme balance.

Frequently asked questions

Can I use three-digit HEX?

Yes. Three-digit HEX values are expanded to six digits.

Does it generate CSS variables?

Yes. Copy the generated variables and rename them for your design system.

Should I still check contrast?

Yes. Use Contrast Checker for foreground and background pairs.

Does it upload colors?

No. Everything runs locally.
