ColorZilla is a Firefox add-on that brings advanced color analysis to your browser. On Windows it provides an integrated eyedropper and pixel sampler so you can pick colors directly from any page, inspect hex, RGB and HSL values, and copy CSS-ready color codes to the clipboard in a single click. The extension includes a gradient generator, a palette manager and accessibility checks to help you maintain contrast and readability. Designers and developers can extract color values, build and export palettes, refine gradients visually and transfer precise color specs into projects and style sheets. It also stores recent picks, supports multiple color formats for export, and pairs well with developer toolchains to speed handoffs. Installation is lightweight and integrates with Firefox on Windows, adding quick toolbar access and smooth workflow integration. Whether you are prototyping, auditing UI contrast or matching brand colors, this tool speeds up color tasks and helps keep designs consistent across pages and applications. Updates are frequent and the interface is unobtrusive, with keyboard shortcuts and customizable options to match your workflow.

I wish I had discovered ColorZilla sooner! It’s like candy for designers! Features like the color history are super helpful. I honestly can’t get enough of it – every pixel feels perfect now!
