colorexa is a free browser extension for Chrome developed by Rafael Bardini. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This handy tool allows users to quickly lookup colors by typing or highlighting their hexadecimal codes.

With colorexa, users can easily find colors specified as an RGB triplet in hexadecimal format. The extension features a pop-up bubble whose background automatically refreshes to represent the color typed in its text field or highlighted on the page. It supports both full (six-digits) and abbreviated (three-digit) hexadecimal color codes.

This extension proves to be particularly useful when you need to quickly check a color found in the source code of a webpage or a stylesheet. For a live preview, you can visit the extension's website.
