A CSS-based dark theme for the Slack desktop application, installed by injecting custom styles into Slack's local app files. It provides several color scheme presets and lets users customize theme colors via CSS variables.
Use cases
- make Slack dark with higher contrast
- apply a custom dark theme to the Slack desktop app
- customize Slack colors with CSS variables
- reduce eye strain from Slack's light theme
- try alternative Slack color schemes like One Dark
When to choose
- you use an older Slack desktop version and want a true dark theme
- you want full CSS-level control over Slack's appearance
When to avoid
- you use a recent Slack version where the injection hack no longer works
- you don't want to re-apply the hack after every Slack update
- you only need Slack's built-in dark mode
