DevColor Inspector

Professional color picker with modern CSS color space conversion, color-wheel harmony suggestions, and WCAG 2.1 contrast analysis.

DevColor Inspector is a color toolkit for front-end developers and designers. Pick a color from any web page and handle the rest of your color work in a single popup. Use the browser's built-in picker to sample any pixel on screen, or type a color value by hand. Once you have a color, the extension immediately shows the converted result so you can copy it, suggests matching colors based on the one you chose, generates a set of lighter and darker shades you can adjust, checks how readable text will be against its background, and exports those shades as styles you can paste into your project. Every color you capture is kept in a list, where you can pin the ones you want to keep and come back to them later. It runs fully offline, collects no data, contacts no server, and requests minimal permissions.
