Make a custom theme
- In the Theme section, click Customize… (or Edit theme… if a custom theme is already active) to open the theme editor.
- Give it a name and pick a Base theme to start from.
- Adjust colors, grouped into Canvas, UI chrome, and Overlays. Each changed color shows a reset button to return it to the base value.
- A live preview shows the chrome and a miniature canvas. The editor has its own Undo/Redo (Ctrl/Cmd+Z).
- Save theme.
Custom themes appear under a Custom group in the theme picker. To remove one, select it and use Delete.
Other appearance settings live on the same tab: Unit system (Metric/Imperial), Language, and Fabric preset. See Settings.
