How to change the background color of the TabButton in WPF Ribbon?

You can change the Background color of the TabButton in WPF Ribbon by overriding the themes to the control’s style. This can be achieved by adding a corresponding ResourceDictionary in the sample and defining the new style with the BasedOn property. When the ResourceDictionary is added, you can acquire all the settings of the base style, and you can override them as desired. Using this approach, you can override the style for all the controls. Here, an example is illustrated to set the Background for the TabButton by customizing the TabButtonStyle using the BasedOn property.

Syntax for ResourceDictionary

<ResourceDictionary Source="/Syncfusion.Themes.Windows11Light.WPF;component/<ControlName>/<ControlName>.xaml">
</ResourceDictionary>

Step 1 : Add the resource dictionary in MainWindow.xaml

<syncfusion:RibbonWindow.Resources>
  <ResourceDictionary>
      <ResourceDictionary.MergedDictionaries>
          <ResourceDictionary Source="/Syncfusion.Themes.Windows11Light.WPF;component/Ribbon/Ribbon.xaml"/>
      </ResourceDictionary.MergedDictionaries>
      <Style x:Key="ribbonTab" TargetType="syncfusion:TabButton" BasedOn="{StaticResource SyncfusionTabButtonStyle}">
          <Setter Property="Background" Value="Transparent"/>
      </Style>
  </ResourceDictionary>
</syncfusion:RibbonWindow.Resources> 

Syntax for BasedOn

BasedOn="{StaticResource Syncfusion<ControlName>Style}"

Step 2 : Define the new style using BasedOn property

<syncfusion:RibbonWindow x:Class="WpfApp1.MainWindow"
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
      xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
      xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
      xmlns:local="clr-namespace:WpfApp1" xmlns:syncfusion="http://schemas.syncfusion.com/wpf"
      mc:Ignorable="d"  xmlns:syncfusionskin ="clr-namespace:Syncfusion.SfSkinManager;assembly=Syncfusion.SfSkinManager.WPF" 
                       syncfusionskin:SfSkinManager.Theme="{syncfusionskin:SkinManagerExtension ThemeName=Windows11Light}"
      Title="MainWindow" Height="450" Width="800">
  <syncfusion:RibbonWindow.Resources>
      <ResourceDictionary>
          <ResourceDictionary.MergedDictionaries>
              <ResourceDictionary Source="/Syncfusion.Themes.Windows11Light.WPF;component/Ribbon/Ribbon.xaml"/>
          </ResourceDictionary.MergedDictionaries>
          <Style x:Key="ribbonTab" TargetType="syncfusion:TabButton" BasedOn="{StaticResource SyncfusionTabButtonStyle}">
              <Setter Property="Background" Value="BlueViolet"/>
          </Style>
      </ResourceDictionary>
  </syncfusion:RibbonWindow.Resources>
  <Grid>
      <syncfusion:Ribbon x:Name="_ribbon" VerticalAlignment="Top" >
          <syncfusion:RibbonTab Caption="HOME"  IsChecked="True"  TabButtonStyle="{StaticResource ribbonTab}">
