TAdvOfficePager Tab Appearance

Hello,
I create the pages for AdvOfficePager dynamically at runtime.
The AdvOfficePager component is linked to a officestyler, eg. Win10.

At runtime I want to create new pages with random color for the Tab-Headers, but

MainTabOfficePager.AddAdvPage(caption);
...
MainTabOfficePager.ActivePage.TabHint:=caption;
MainTabOfficePager.ActivePage.TabAppearance.Color:=Random($1000000);

is not working (and not with other random color  functions too, like merging RGB). The styler-style seems to be static.

Someone has any idea? Thank you for suggestions.
Frank

For the pages where you want to have the tab appearance deviate from the styler controlled tab appearance, set AdvOfficePage.UseTabAppearance = true
