change the current site background to your desired color
Most color-changing extensions require the "read and change all your data on all site" permission, which is overkill and raises privacy concerns. This particular extension does only one thing: it changes the background color of the current site, that's all.
No special permissions are required, no data is collected, and no privacy concerns.
