Themes

Termy ships 800+ built-in themes from iTerm2-Color-Schemes, plus its own termy and termy-light. Search and pick one in Settings or with Switch Theme in the command palette, or set it by id:

theme = catppuccin-mocha

termy -list-themes prints every id.

Custom themes

Drop .json files in ~/.config/termy/themes/ (Windows: %APPDATA%\termy\themes\). The filename (without .json) is the theme id, and a file named like a built-in theme replaces it:

theme = my-theme

Or pick one from Switch Theme in the command palette.

Format

{
  "background": "#0b1020",
  "foreground": "#e7ebf5",
  "cursor": "#a7e9a3",
  "black": "#0b1020",
  "red": "#f1b8c5",
  "green": "#a7e9a3"
}

All keys are 6-digit hex. See Colors for the full list.

Import without switching theme

Import Colors in the command palette writes values into [colors] while keeping your current theme — useful for one-off tweaks.

Delete [colors] to fall back to the pure theme file.
