Chromapicker - Color Picker & Mixer

Pick colors from any web page, extract entire page palettes, mix your own unique shades. Alt+P to pick anywhere.

Chromapicker is a complete color picker for developers and designers who work on the web. Capture any color displayed on screen with the native EyeDropper API (Alt+P shortcut), extract the full palette of a page (every color actually used in the DOM) or the dominant colors of a local image (k-means algorithm). Mix two colors in RGB, HSL or OKLCH (perceptually uniform blending), generate color harmonies (complementary, analogous, triadic, split, tetradic, monochromatic), build multi-stop CSS gradients visually, or create an 11-step tonal scale ready to drop into a design system, with automatic WCAG annotations. Seven color formats available in one click: HEX, RGB, HSL, OKLCH, CIE Lab, CMYK and display-p3. Built-in indicators: WCAG + APCA contrast, CIEDE2000 ΔE, color blindness simulation (deuteranopia / protanopia / tritanopia), wide-gamut (P3) detection on the current page. Interface available in English, French, German and Portuguese (auto-detected from your browser language). No telemetry, no external data transmission - everything runs locally in the browser.
