Shademix — Color Picker

About

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.
