v1.0.0 — First Stable Release

OpenPalette is a local-first, open-source color workspace for designers and developers. Everything runs in your browser — no accounts, no tracking, no cloud.

What is OpenPalette?

A complete color workspace with nine integrated tools that share a single palette. Generate palettes, check accessibility, build token scales, extract colors from images, create gradients, and export production-ready color systems — all locally on your device.

Features

Studio — Full palette editor with drag-to-reorder swatches, harmony modes, quick-tune sliders, undo/redo, and inline color picker.

Explore — 320 curated palettes across 8 styles and 8 topics. Search, filter, and open any palette directly in the Studio.

Extract — Upload any image and extract a palette in one click. Six extraction modes for any creative direction.

Contrast — WCAG contrast checker with AA/AAA pass/fail grades and smart replacement suggestions.

Visualizer — Preview palettes across 7 real-world templates — hero sections, dashboards, buttons, forms, tables, alerts, and pricing cards.

Colors — A 150-color library organized by category. Browse, search, and copy individual colors.

Tokens — Generate complete design token scales from any base color. Export as CSS Variables, Tailwind Config, JSON Design Tokens, SCSS, Android XML, or iOS Swift.

Gradient — Gradient studio with 14 presets and a full stop editor. Create smooth linear and radial gradients.

Accessibility — Contrast matrix, color blindness simulation (protanopia, deuteranopia, tritanopia, achromatopsia), theme pair tester, typography contrast, and full audit checklist.

Platform
