### Base theme
Obsidian comes with two base themes, light and dark. This option sets the default color scheme your theme uses to either display its light or dark mode version.
### Custom theme
There are lots of community themes contributed by our amazing community that you can easily choose from.
You can easily tweak it by adding [[CSS snippets]].
### Translucency
You can make the window translucent by enabling this option in the settings appearance tab. Currently this option is only available for Windows and macOS.
There's a known issue under Windows where dragging the window is extremely slow when translucency is enabled. This is due to a Windows bug. A GitHub issue tracking the status of a fix can be found here: https://github.com/riverar/sample-win32-acrylicblur/issues/2
