Night Eye is an extension that intelligently converts the light themes of websites into dark themes. It does much more than just inverting color schemes and the end result is impressive.
It intelligently scans web pages to know how to switch an entire website into dark mode. You can also customize specific colors on websites to make them fit easier into a dark theme.
For example, if Night Eye switches a yellow to green, you can make that shade of yellow stay yellow or pick another color that shows up better against a dark background.
It's one of the best extensions for Microsoft Edge
