Themes

Two themes ship out of the box: Default Dark and GitHub Dark. Select either from Settings › Appearance; a live preview renders below the selector.

Custom themes

Place a .verne.json theme file in ~/.verne/. Verne picks it up and adds it to the theme selector, with no restart needed.

Each file describes one mode. Top-level name and type (dark or light) label it, and four sections set the colors:

Section	What it sets
`ui`	shadcn UI color roles (the keys without their leading `--`).
`editor`	Monaco editor colors, using VS Code’s `colors` keys.
`terminal`	The xterm palette: background, foreground, cursor, selection, and the 16 ANSI colors.
`syntax`	TextMate scope rules for code highlighting.

A trimmed example follows. For every key, see the full Verne Dark theme file:
