About Color Picker Lab
Color Picker Lab is a free color toolkit for designers and developers. Pick a color and get every format you need — HEX, RGB, HSL, HSV, CMYK, and OKLCH — copy it in one click, build palettes, check accessibility, and export to code. No signup, no clutter, and your colors are processed entirely in your browser.
Why we built it
Most color tools are either dated and ad-heavy or hide useful features behind a paywall. Color Picker Lab is fast, modern, and free, and it supports the things professionals actually need in 2026 — alpha/transparency, OKLCH, live WCAG contrast, and clean exports. It stays deliberately open: no signup, no paywall, and fully readable by search engines and AI answer engines.
Accuracy
Every conversion and contrast result is computed with standard color-science formulas (sRGB, OKLab/OKLCH, and the WCAG 2.1 contrast algorithm). If you ever spot a value that looks off, tell us — accuracy is the point.
Privacy
Your colors and images never leave your device. See our Privacy page for details.
