Scanning through a CSS file or a chunk of design documentation to manually find every hex color code used is tedious, especially in a larger file with colors scattered throughout many rules.
This tool scans any pasted text or code for valid hex color patterns (both 3-digit and 6-digit formats with a leading #) and lists every unique match found, each shown alongside a small color swatch preview.
This is useful for auditing a stylesheet's color palette at a glance, pulling together a design system's color inventory from existing CSS, or quickly checking which specific hex values appear in a piece of code.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.
The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.
Unlike a heavier desktop application, there's nothing to download, update, or configure before you can start using this tool.
