Curlor is a free Chrome add-on developed by Arthur Gartner. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. Curlor is designed to change the color of text hex, rgb, and hsl values to their respective colors within the browser window.

With Curlor, users can automatically change the text color, background, or both of hex, rgb, and hsl values displayed within the browser. This can be done either automatically or upon cursor hover, providing a convenient way to view the actual colors represented by these text values in real time.

One potential issue with Curlor is that it works by traversing the DOM for each visited website. Depending on the framework used, this may cause compatibility issues with certain sites. However, Curlor includes a whitelist capability, allowing users to quickly add domains to the whitelist. This ensures that the extension does not need to be completely disabled when encountering issues caused by DOM traversal.

Curlor is a useful tool for anyone working with color text values, providing an easy and efficient way to visualize the actual colors within the browser window.
