Visually pick colors, extract dominant palettes from uploaded photos or logos, sample desktop pixels with the screen eyedropper, and evaluate WCAG 2.1 accessibility contrast in real time.
Intuitive, friction-free workflow designed to get you from input to accurate results in seconds.
Drag the color sliders, click the swatch, or type a hex code in Visual Picker mode.
Switch to Extract from Image to upload any photo, screenshot, or graphic to sample pixels and generate a 6-color palette.
Browse Harmonies & Schemes to generate complementary, analogous, triadic, and monochromatic color pairings.
Check the live WCAG contrast card to verify legibility against white and black backgrounds.
Engineered for speed, privacy, and browser-first accuracy

Authoritative standards, practical benchmarks, and best practices.
A color picker helps you explore palettes and copy exact values into CSS, Figma or Tailwind config. Beyond aesthetics, contrast ratio matters for accessibility. WCAG recommends at least 4.5:1 contrast for normal text against its background.
HEX is the default on the web. RGB maps to screens. HSL makes it easier to adjust lightness without shifting hue. Pick a base color, then copy all three formats for your design system documentation.
Straightforward answers regarding color picker calculations, platform limits, and data privacy.
You can drag and drop any image (PNG, JPG, SVG, WebP) directly into the browser. An HTML5 canvas samples pixels locally with an interactive loupe and extracts the top 6 dominant colors using color quantization. No files are uploaded to any server.
The screen eyedropper uses the W3C EyeDropper API, currently supported in Chromium-based browsers like Google Chrome, Microsoft Edge, and Opera. If your browser does not support it, you can use our built-in Visual Picker or Image Extractor.
WCAG 2.1 Level AA requires a contrast ratio of at least 4.5:1 for normal body text and 3:1 for large text (18pt or 14pt bold). Level AAA requires 7:1 for normal text and 4.5:1 for large text. Our contrast calculator grades both automatically.
An 8-digit HEX code includes an alpha (opacity) channel where the last two hex digits represent transparency from 00 (0% opacity) to FF (100% opacity). Standard 6-digit HEX represents pure RGB.
Adjust the hue, saturation, and lightness sliders or paste an image to sample colors. The tool shows the exact 6-digit HEX code with one-click copy straight into your stylesheet or design software.
Yes. Switch to the Harmonies & Schemes tab to see your base color mapped into complementary, analogous, triadic, tetradic, split complementary, and monochromatic palette variants with instant copy buttons.
