          </Track.IncreaseRepeatButton> 
          <Track.Thumb> 
           <Thumb x:Name="Thumb" Style="{StaticResource CustomThumbForSlider}" Background="Black"/> 
          </Track.Thumb> 
         </Track>

你應該做在你SliderRepeatButtonStyle風格。 背景屬性定義了軌道內側部分的顏色，BorderBrush屬性定義了軌道邊框的顏色。

<Style x:Key="SliderRepeatButtonStyle" TargetType="RepeatButton"> 
    <Setter Property="SnapsToDevicePixels" Value="true" /> 
    <Setter Property="OverridesDefaultStyle" Value="true" /> 
    <Setter Property="Template"> 
     <Setter.Value> 
      <ControlTemplate TargetType="RepeatButton"> 
       <Border SnapsToDevicePixels="True" Background="Red" BorderThickness="1" BorderBrush="OrangeRed" Height="3"/> 
      </ControlTemplate> 
     </Setter.Value> 
    </Setter> 
</Style>
