Themes & appearance

Nexis is highly themeable — from the editor palette down to the terminal colors and the file-explorer icons.

Built-in themes

Ships with: Nexis Default, Catppuccin Mocha, Nord, Tokyo Night, Rosé Pine, Gruvbox, Caffeine, Claude, Sage, and Tide. Each theme carries its own terminal color palette.

Custom themes

• Create, import, and delete .nexis-theme files.
• A live swatch preview shows colors as you pick them.
• The theme editor opens any .nexis-theme directly in the code editor, so a theme is just a file you can version and share.

Backgrounds

Set a background image with adjustable opacity (0–100%) and blur (0–64 px) for a personalized workspace.

Icon themes

The file explorer supports Catppuccin and Material icon themes, with a vscode-icons fallback so ecosystem folders (NuGet, Maven, Kotlin, iOS, Flutter, MongoDB, and more) still get purpose-built art.

Configuring

Themes are set under Settings → Appearance. See configuration → themes for details on authoring your own.
