About this extension
Shadeflip remembers Dark or Light for each site you visit.
Pages are flipped with a colour-inverting filter; images and videos are flipped back so they look normal.
Open source: https://github.com/nxame/shadeflip
- One click per site. Click the toolbar button, or press Alt+Shift+D, and the current site flips. Every other site stays as it was.
- Leaves matching sites alone. Shadeflip measures how bright a page really is, so if you picked Dark and the site is already dark, nothing changes.
- Works both ways. It can make bright sites dark and dark sites light.
- Settings: pick a default for sites you haven't set (Off, Dark everywhere, Light everywhere) and edit or remove any site you've set.
- Tiny and private. Under 20 KB, no dependencies, no tracking, no nagging. Flips in private windows are never saved.
