Shademix — Color Picker

Auto-extract a site's dominant colours, see OKLCH harmonies, build a palette, eyedrop any pixel, and export. Free, no signup.

Shademix turns any web page into a colour palette in one click. Open the popup and Shademix instantly reads the page and shows its dominant colours — no clicking required. Pick a main colour, see it in HEX, RGB, HSL and OKLCH (tap any format to copy), and explore seven OKLCH-perceptual harmonies (monochromatic, complementary, analogous, triadic, tetradic, split-complementary, square). • Auto dominant-colour extraction from the visible page • Main colour with HEX / RGB / HSL / OKLCH — click to copy • 7 OKLCH harmonies of the main colour — click any swatch to copy or add • Eyedrop any pixel (native EyeDropper) into 5 manual slots • Build a palette and export it: HEX list, CSS variables, JSON, Tailwind config, or SVG swatches • "Download everything" — main + every dominant + every harmony in one file • Click any colour anywhere to copy its code Free. No signup. No telemetry. No ads. Everything runs locally in your browser — the extension talks to nothing. Part of the Shademix colour toolkit, also on the web (shademix.com) and on iPhone, iPad, Mac and Apple Vision Pro via the App Store.
