What is Color Palette Generator?

Color Palette Generator is a web application for designers and frontend developers to create harmonized 5-color palettes, inspect WCAG 2.1 AA/AAA contrast ratios, and export design tokens.

It supports color harmony rules including Analogous, Monochromatic, Triadic, Complementary, and Split-Complementary, enabling rapid exploration of cohesive brand schemes.

One-click export options allow you to copy generated color palettes directly as CSS variables (HEX / HSL), Tailwind CSS configuration objects, or JSON tokens.

Privacy Guarantee: Color palette generation and contrast ratio calculations execute 100% locally in browser memory.

Frequently Asked Questions

How are color harmony rules generated?
Harmonies are calculated algorithmically in HSL color space by rotating hue angles (e.g. 180° for Complementary, 120° for Triadic) while adjusting saturation and lightness.
What is WCAG AA/AAA contrast ratio compliance?
WCAG contrast compliance measures luminosity ratio between text and background colors. Ratio 4.5:1 passes AA for normal text, while 7:1 passes AAA.
Can I export generated color palettes to Tailwind CSS or CSS variables?
Yes! Click "Export Palette" to copy pre-formatted CSS custom properties (:root { --color-1: ... }) or Tailwind CSS theme objects.
How do I lock specific colors while generating new palettes?
Click the padlock icon on any color card to freeze its value. Clicking "Generate Palette" or pressing Spacebar will regenerate only unlocked color slots.
Is this color palette generator 100% client-side?
Yes! All color calculations, contrast checks, and token formatting run locally in client JavaScript.
