Pick or make a theme

Open Settings › Appearance. Choose one of the 37 built-in themes or 13 snippets, or open the editor to change any color, font, radius, shadow, glass layer or background. Every built-in theme is tested for readable text in each mode it ships, and Signal is the 1.0 look, rebuilt on the new system.

Kernel Night is the dark default and Daylight the light one, and from 24 October to 1 November Spectral and Bone take their place. The theme applies to the app; RoachNet Setup always uses Kernel Night.

Themes are files

A theme is a JSON file. Export one to share it, or import one from someone else. RoachNet also watches its themes folder, ~/RoachNet/storage/themes: drop a theme file in and it appears. An imported theme's background picture must be a picture inside the theme's own folder, or the import is refused, and a copy of a theme lists "You" as its author until you set your own in the editor.

Theme packs

Theme packs install from RoachNet Apps, starting with the Halloween Collection and Retro Terminals; version 1.1.0 of each needs RoachNet 1.1.1. Their themes appear in Settings › Appearance.

On your phone

With RoachNet 1.1, the iOS companion (0.3.0 or later) follows the theme you picked on the Mac, light themes included. Turn that off under Connection › Appearance on the phone.

Motion

Animated and dithered backgrounds stop when Reduce Motion is on in macOS.
