colorScheme property
The color scheme of the page.
If unset, the color scheme is inherited from a parent page. If the page
has no parent, the color scheme uses a default Slides color scheme,
matching the defaults in the Slides editor. Only the concrete colors of
the first 12 ThemeColorTypes are editable. In addition, only the color
scheme on Master pages can be updated. To update the field, a color
scheme containing mappings from all the first 12 ThemeColorTypes to their
concrete colors must be provided. Colors for the remaining ThemeColorTypes
will be ignored.
Implementation
ColorScheme? colorScheme;
