Themes

Nexis themes control the editor palette, terminal colors, and overall UI accent. For the list of built-ins and a feature overview, see Themes & appearance.

Switching themes

Open Settings → Appearance and pick a built-in theme: Nexis Default, Catppuccin Mocha, Nord, Tokyo Night, Rosé Pine, Gruvbox, Caffeine, Claude, Sage, or Tide. Each includes a matching terminal color palette.

Authoring a custom theme

A theme is a .nexis-theme file — a plain, shareable document you can keep under version control.

1. In Settings → Appearance, create a new theme or import an existing .nexis-theme.
2. Edit colors with the live swatch preview to see changes as you go, or open the file in the theme editor (the code editor) for direct editing.
3. Save. Import, export, and delete themes from the same panel.

Background image

Alongside the color theme you can set a background image with:

• Opacity — 0–100%.
• Blur — 0–64 px.

Icon themes

Choose Catppuccin or Material file-explorer icons, with a vscode-icons fallback for ecosystem-specific folders.
