Theme Color

You can customize your active Visual Studio Code color theme with the workbench.colorCustomizations user setting.

{
  "workbench.colorCustomizations": {
    "activityBar.background": "#00AA00"
  }
}

Note: If you want to use an existing color theme, see Color Themes where you'll learn how to set the active color theme through the Preferences: Color Theme dropdown (⌘K ⌘T (Windows, Linux Ctrl+K Ctrl+T)).

Theme colors are available as CSS variables in webviews, and an extension is available which provides IntelliSense for them.

Color formats

Color values can be defined in the RGB color model with an alpha channel for transparency. As format, the following hexadecimal notations are supported: #RGB, #RGBA, #RRGGBB and #RRGGBBAA. R (red), G (green), B (blue), and A (alpha) are hexadecimal characters (0-9, a-f or A-F). The three-digit notation (#RGB) is a shorter version of the six-digit form (#RRGGBB) and the four-digit RGB notation (#RGBA) is a shorter version of the eight-digit form (#RRGGBBAA). For example #e35f is the same color as #ee3355ff.

If no alpha value is defined, it defaults to ff (opaque, no transparency). If alpha is set to 00, the color is fully transparent.

Some colors should not be opaque in order to not cover other annotations. Check the color descriptions to see to which colors this applies.
