Builtin Themes

Help query: "What are the builtin themes?" / "What themes does Volt ship with?" / "List Volt themes"

Volt ships eight named color themes as TOML files under user/themes/. Shared editor options (font, scrolloff, language defaults, window transparency) live separately in user/themes/global.toml — that file is not a selectable theme.

Builtin theme list

Theme id	Display name	File
gruvbox-dark	Gruvbox Dark	user/themes/gruvbox-dark.toml
gruvbox-light	Gruvbox Light	user/themes/gruvbox-light.toml
rosepine-dark	RosePine Dark	user/themes/rosepine-dark.toml
volt-arc	Volt Arc	user/themes/volt-arc.toml
volt-dark	Volt Dark	user/themes/volt-dark.toml
volt-light	Volt Light	user/themes/volt-light.toml
vscode-dark	VS Code Dark	user/themes/vscode-dark.toml
vscode-light	VS Code Light	user/themes/vscode-light.toml

Each named theme file declares:

id = "gruvbox-dark"
name = "Gruvbox Dark"

[pallet]
# …palette colors…

[tokens]
# …token → palette mappings…

(pallet and palette are both accepted section names.)

Default theme

The default theme id is selected in user/theme.rs:

const DEFAULT_THEME_ID: &str = "gruvbox-dark";

Changing that constant requires rebuilding volt-user. Switching themes interactively does not.

How to switch themes

1. Open the theme picker with F6 (default keymap), or run the themes picker command from the command palette
2. Or change DEFAULT_THEME_ID and rebuild the user package

See Change theme and font for fonts, global.toml options, and editing colors.

Not a theme: global.toml

user/themes/global.toml holds shared options applied across themes, for example:

• font, font_size, emoji font settings
• scrolloff, cursor/corner roundness
• window.transparency (none, blur, acrylic, mica, mica-tabbed)
• per-language defaults under [langs.*]
