Themes

Change color, type and control styling across a whole document.

A theme is the set of colors and type settings a document draws from. Controls refer to theme tokens — primary, warning, base-content — rather than to literal colors, so changing the theme restyles every screen at once and keeps the result coherent.

A control set to the error variant follows the theme; a control given a literal color keeps that color.

Adjusting the theme

Open the Theme panel.
Change a token and watch the canvas update.
Save the document to keep it.

The canvas renders with the theme applied, so the editor shows what the runtime will draw.

Reusing a theme

Themes export from the Theme panel as a .thm file, which imports into any other document.

Button — variants, and setting colors directly.
USB import & export — moving a .thm between documents.
