Appearance & themes

Altretta's appearance settings control the theme, the accent colour, your fonts, and any custom CSS you want to layer on top — so the app looks the way you want to work.

Theme

Three options: Dark, Light, and Auto, which follows your operating system and switches with it. The whole app — editor, graph, panels, and docks — follows your choice.

Accent colour

Choose an accent colour to personalise highlights, active states, and interactive elements across the interface. Six presets are offered — cyan, blue, purple, green, red and amber — and you can enter any colour you like instead. It's a cosmetic preference and doesn't change any verification behaviour.

Fonts & custom CSS

Appearance also covers typography: set the interface font and the editor font independently, so reading and writing feel the way you want without changing the app's chrome.

For finer control, Altretta accepts a custom CSS snippet — drop in your own styles to restyle the app beyond the built-in themes and accents. Your snippet can use Altretta's own theme variables, so a tweak can follow the light/dark switch instead of fighting it.

Where these settings live — and how far they reach

The layout itself isn't configured here: you shape it by dragging tabs and splitting panes in the workspace, and Altretta remembers the result. See Tabs, panes & workspaces.
