Tools
Color tools for
design workflow.
Practical utilities that extend what you can do with color. Each tool works standalone with your own custom palette or connects directly to Huelib's curated library.
Palette Generator
Generate beautiful color palettes built on harmony principles. Choose a style, lock the colors you like, regenerate the rest, and refine until it feels right. Works from 2 to 6 colors.
Image to Palette
Upload an image and extract a color palette from it. Choose dominant, vibrant, or muted tones, pick how many colors you want, and take the result into contrast checking, accessibility auditing, and more.
Palette Visualizer
See how a palette performs in real design contexts. Preview colors on app interfaces, brand identity layouts, and editorial compositions. Colors are automatically mapped to roles like background, primary, accent, and text.
Contrast Checker
Check the contrast ratio between any two colors against WCAG AA and AAA standards. Verify readability for normal and large text, and preview your pairing in context.
Semantic Token Mapper
Take any Huelib palette and assign colors to semantic roles like primary, background, text, and accent. Export as CSS variables, JSON tokens, or copy individual mappings.
Color Blindness Simulator
Simulate how a palette looks under protanopia, deuteranopia, tritanopia, and achromatopsia. Identify where colors may collapse and make more accessible design choices.
Palette Accessibility Audit
Audit an entire palette against WCAG contrast standards. Surface the strongest readable pairings, identify weak spots, and understand your palette's accessibility profile. Works with Huelib palettes or your own custom colors.
Tools work best with a palette. Start by finding one you like.
