ColorZilla Review — Pixel-Accurate Colour Picker for Any Webpage
ColorZilla lets you click any pixel on any webpage and copy its exact colour code in hex, RGB, or HSL format. It is the most widely installed colour picker extension on the Chrome Web Store, with over 3 million users. Thumbnail designers, brand builders, and anyone who works with visual content use it to extract colours from competitor pages, design references, and existing assets without guessing.
Install on Chrome Web Store →Key Features
The eyedropper tool activates with one click and lets you sample the exact colour of any pixel visible on a webpage. The hex code is copied to your clipboard immediately — usable in Canva, Photoshop, Figma, or any design tool without manual conversion.
Colour history keeps a record of the last colours you sampled in the current session. If you're building a colour palette from multiple pages — capturing a competitor's brand colours from different elements — the history lets you review and copy previous samples without revisiting each page.
A gradient generator tool lets you build CSS linear gradients and copy the code directly. Creators building thumbnail backgrounds or landing page designs can construct gradient colour schemes without switching to an external tool.
The CSS colour analyser reads all colour values used on the current page and lists them in order of frequency. This is useful for understanding a competitor's brand colour hierarchy — what their primary, secondary, and accent colours are — from a single analysis.
Who Is It For
Creators who design thumbnails, channel art, or any visual content and want to match colours from references, competitor pages, or brand guidelines. Thumbnail designers who work from colour references will find this saves manual colour matching work constantly.
Creators who don't do visual design work — those focused entirely on video filming, podcast content, or text-based creation — will have little use for a colour picker. Also worth noting: ColorZilla only samples from browser content, not desktop applications or images in external software.

Summary
Worth installing for any creator who does visual design work in their browser.

One of the most immediately useful design utilities available as a Chrome extension.
