Using themes

Themes reskin Carbon (colors, glass, sidebar, optional animated backdrops). They do not patch Roblox. Use mods for in-game assets.

Pick a theme

1. Settings → Appearance.
2. Choose a built-in theme or a community pack from the list.
3. Optional: open theme settings for per-theme options when the manifest defines them.

Selection persists across restarts. Built-in themes ship with the app; community themes live in themes/<theme-id>/ with a theme.yaml manifest.

Install a community theme

1. Download or author a folder containing theme.yaml and the referenced stylesheet (often .scss or .css).
2. Copy the folder into themes/ (name = theme id).
3. Restart Carbon or refresh themes if the UI offers it, the new entry should appear under Appearance.

What you will notice

Theme type	Effect
Token pack	--crbn-* colors, surfaces, accents on the shell
Icons	Custom sidebar or UI SVG overrides
JS backdrop	Animated canvas/WebGL behind frosted panels (javascript.enabled in manifest)

Windows Mica/acrylic backdrops come from configuration.backdrop unless a backdrop-layer JS theme takes over.
