Changing the background of the Ribbon
can’t be done by simply changing the Background
property.
You have to, at least, overwrite the following resources to change the background of the Ribbon
:
<Fluent:RibbonWindow.Resources>
<SolidColorBrush x:Key="Fluent.Ribbon.Brushes.RibbonTabControl.Background">LightBlue</SolidColorBrush>
<SolidColorBrush x:Key="Fluent.Ribbon.Brushes.RibbonTabControl.TabsGrid.Background">LightBlue</SolidColorBrush>
<SolidColorBrush x:Key="Fluent.Ribbon.Brushes.RibbonTabControl.Content.Background">LightBlue</SolidColorBrush>
<SolidColorBrush x:Key="Fluent.Ribbon.Brushes.RibbonWindow.TitleBackground">LightBlue</SolidColorBrush>
</Fluent:RibbonWindow.Resources>
