Customize the theme

Change the theme when the canvas is hard to read where you work, or when you want your thread colors to stand out against a darker or lighter background. A theme changes only how the app looks, never your design or its stitches. Boldbobbin ships with several light and dark themes; the default is Boldbobbin, a light one.

Switch theme

Settings → Appearance & Units → Theme. Click a theme swatch (grouped under Light and Dark). The change previews live and commits when you click Save.

Make a custom theme

1. In the Theme section, click Customize… (or Edit theme… if a custom theme is already active) to open the theme editor.
2. Give it a name and pick a Base theme to start from.
3. Adjust colors, grouped into Canvas, UI chrome, and Overlays. Each changed color shows a reset button to return it to the base value.
4. A live preview shows the chrome and a miniature canvas. The editor has its own Undo/Redo (Ctrl/Cmd+Z).
5. Save theme. Boldbobbin switches to the new theme straight away.

Custom themes appear under a Custom group in the theme picker. To remove one, select it and use Delete.

Example: a dark canvas for white thread

You digitize a lot of white and cream thread, and it is hard to see on the light canvas.

1. Settings → Appearance & Units → Theme, click Midnight or Dark under Dark, and click Save.
2. If you would rather keep the light panels and darken only the canvas, click Customize…, pick Boldbobbin as the Base theme, and change the first color under Canvas (labeled canvasBg, the canvas background).
3. Name it, say "Light with dark canvas", and click Save theme. Boldbobbin switches to it straight away.

Other appearance settings live on the same tab: Unit system (Metric/Imperial), Language, and Fabric preset. See Settings.
