A theme in shades of blue-grey adapted for Firefox.
Coldark is a theme in shades of blue-grey, available in dark and light versions. Its colors have been carefully chosen to offer sufficient reading comfort in most situations.
This variant is designed for Firefox. Although, Coldark uses 16 colors, the Firefox version only uses 7. Some elements do not seem customizable like the tab hover or the search box on the new tab page.
- Detects if the user prefers the dark theme and automatically applies the dark version.
- Allows you to switch between versions using an icon in the navigation bar.
- Allows you to switch between versions using a shortcut (defaults to Alt+T).
If the shortcut doesn't work, check that it's not being used by another extension. If necessary, replace the shortcut either for Coldark or for the other extension.
Firefox uses a small subset of the Coldark palette.
