colors

The bar's colors: the ambient theme's main-toolbar scheme with the XML pspdf__contextualToolbarStyle attributes — background, icon, activated icon and submenu background — laid over it, which is what the View bars painted. The bar reuses MainToolbarColors because its buttons and submenu sheet are the main toolbar's; popup is the submenu sheet's background. Override one with copy: NutrientContextualToolbarDefaults.colors().copy(backgroundColor = …).
