Change content color is a free Chrome extension developed by Jeff T. that falls under the category of Browsers and the subcategory of Add-ons & Tools. This extension allows users to change the background color of webpages to a warm color for a more comfortable browsing experience.

With Change content color, users can simply double click on any region of a webpage to change its background color to a warm hue. This feature is especially useful for those who find white backgrounds too harsh on their eyes during long periods of web surfing.

It is important to note that not all webpages can have their content color changed. Some webpages have high security measures in place that prevent general scripts from modifying their colors. However, the extension supports URLs starting with ftp as of version 1.1 and allows for changing more areas in version 1.2.

Overall, Change content color is a handy Chrome extension for those looking to customize their browsing experience by adjusting webpage background colors.
