Chrome extension that restores the beloved Dim (dark blue) background theme on X/Twitter and Grok, replacing the harsh pure black "Lights Out" background with the original soft dark blue (#15202B).
- Go to the Chrome Web Store page
- Click "Add to Chrome"
- On X/Twitter, set your theme to "Lights Out" (Settings > Display > Lights Out)
- On Grok, set your theme to dark mode
- Click the extension icon to toggle Dim on/off for each site independently
- Restores the Dim (dark blue) background on X/Twitter
- Restores the Dim (dark blue) background on Grok
- Independent toggles for each site
- Pure CSS overrides — lightweight and fast
- No data collection, no tracking, no analytics
- X/Twitter must be set to "Lights Out" (dark) mode
- Grok must be in dark mode
- The Dim theme activates on top of the existing dark mode
The extension applies CSS overrides on top of the existing dark mode:
- X/Twitter: Targets known utility class selectors and inline styles to replace black backgrounds with Dim blue equivalents.
- Grok: Overrides the native
--surface-*CSS variables with Dim blue HSL values.
No DOM elements are injected or modified. No JavaScript hooks into site functionality.
