          <Track.DecreaseRepeatButton >
                                <RepeatButton    Style="{StaticResource    SliderRepeatButtonStyle}" Command="{x:Static Slider.DecreaseLarge}"/>

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

您应该以 SliderRepeatButtonStyle 样式执行此操作。背景属性定义轨道内部的颜色， BorderBrush 属性定义轨道边框的颜色。

<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>
