ColourMail is a Chrome extension developed by adamfoot16, available for free in the Browsers category under Add-ons & Tools. This extension aims to enhance the user experience of Outlook by allowing users to customize the background color of various elements on the web page. By simply Right-Clicking anywhere on the screen, users can easily change the background color, making text more readable and reducing eye strain.

At present, ColourMail offers only one background color and text option, with a promise from the developer to introduce additional color variants in future updates. This extension serves as a simple yet practical tool for users looking to personalize their Outlook experience for improved readability and visual comfort.
