What is the Color Palette Generator?

A palette generator builds 5-color schemes from a base color using 7 color-theory harmonies (monochrome, complementary, analogous, triadic, tetradic, split-complementary, shades). This one also extracts colors from uploaded images and validates every pair against WCAG 2.1 contrast requirements (AA and AAA, normal + large text).

Most palette tools focus on aesthetics. This one ships a one-click WCAG audit, so a palette that looks great visually also passes accessibility before it ships. Exports CSS variables, Tailwind config (v3 + v4 with OKLCH), SCSS, JSON design tokens, SVG swatches, and Figma Tokens Studio format.

How it works

Step 1
Pick base + harmony
Drop a HEX, click the wheel, or upload an image to extract a base color.
Step 2
Generate
Spacebar regenerates unlocked swatches. Lock the ones you want to keep.
Step 3
Audit + export
WCAG ratings render inline. Copy as CSS, Tailwind, JSON, or SVG.

Frequently asked questions

Is the color palette generator free?▾

Yes. Unlimited use, no signup. Coolors charges $3-12/month for unlimited palettes + image extract; Adobe Color is free but locked into Creative Cloud sync. This one runs entirely in your browser.

Which harmonies does it support?▾

Seven: Monochrome (single hue, varying lightness), Complementary (base + opposite), Analogous (three adjacent hues), Triadic (three hues 120° apart), Tetradic (four hues 90° apart), Split-complementary, and Shades (Tailwind-style 50→950 ramp).

Can I extract colors from an image?▾

Yes. Drop a PNG, JPG, or WebP and we extract the dominant 5 colors via histogram quantization. Runs in browser -your image never leaves your device.

Does it check WCAG contrast?▾

Yes. Every swatch shows its contrast against black and white, plus AA / AAA / Fail badges for normal (4.5:1, 7:1) and large text (3:1, 4.5:1). Pick combos that pass for accessible UI.

Which export formats are supported?▾

Six: CSS custom properties (--color-1), Tailwind config snippet, SCSS variables, JSON (design-token shape), SVG swatch strip, and Figma Tokens Studio format. One-click copy each.

Does it work with Tailwind v4?▾

Yes. The Tailwind export includes both v3 (tailwind.config.js extend) and v4 (@theme inline) shapes. OKLCH preview is included for v4 users.

What's WCAG AA vs AAA?▾

WCAG 2.1 contrast standard. AA: 4.5:1 for normal text, 3:1 for large (18pt+). AAA: 7:1 normal, 4.5:1 large. AA is the legal minimum (ADA, EAA); AAA is the gold standard.

Can I lock specific colors and regenerate?▾

Yes. Click the lock icon on any swatch; press space or click Generate to regenerate only the unlocked ones. Same Coolors flow, no signup.

Is my data private?▾

Yes. Math + image processing run in your browser. Uploaded images, color values, exported palettes all stay on your device.

Can I save palettes?▾

Use the export buttons (CSS / Tailwind / JSON / SVG) to download. No accounts means no saved-palette gallery, but the JSON export is the standard exchange format for design tokens -import into Style Dictionary, Figma Tokens, or your own design system.
