 {% call macro.prop('getColorScheme', '() => ("dark" | "light")') %}
 You can use the Appearance module to determine if the user prefers a dark color scheme. Although the color scheme is available immediately, this may change (e.g. scheduled color scheme change at sunrise or sunset). Any rendering logic or styles that depend on the user preferred color scheme should try to call this function on every render, rather than caching the value.

+Override the color scheme for the application. Use `"auto"` to remove the override and follow the user's preferred color scheme again.
