WPF Mouseover重置控制顏色

我正在爲單選按鈕創建樣式，並在單擊時更改單選按鈕的顏色。但是，我想使它成爲這樣的樣子，當你單選按鈕時，它也會改變顏色。我已經實現了基本功能，但是當單選按鈕已經被選中（並且因此具有不同的顏色）時，如果它獲得mouseover，則顏色變爲該新顏色，並且當mouseover完成（鼠標離開它）時，顏色可以追溯到原始的未選定顏色。WPF Mouseover重置控制顏色

有沒有一種方法讓它知道什麼時候點擊了正確的顏色？（該的TargetName Border僅僅是一個邊界類）

<Style x:Key="MyRadioButton" TargetType="{x:Type RadioButton}"> 
    <Setter Property="SnapsToDevicePixels" Value="true" /> 
    <Setter Property="FocusVisualStyle" Value="{DynamicResource RadioButtonFocusVisual}" />

使用此Style，並放置兩個差異RadioButton s到測試Unchecked狀態：

<Style TargetType="{x:Type RadioButton}"> 
      <Setter Property="SnapsToDevicePixels" Value="true" /> 
      <Setter Property="FocusVisualStyle" Value="{DynamicResource RadioButtonFocusVisual}" /> 
      <Setter Property="Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="{x:Type RadioButton}"> 
         <BulletDecorator Background="Transparent"> 

          <BulletDecorator.Bullet> 
           <Grid Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"> 

            <Border x:Name="Border" Margin="1" CornerRadius="5" HorizontalAlignment="Center" 
             Width="50" Padding="2" SnapsToDevicePixels="true"> 
             <Border.Background> 
              <VisualBrush> 
               <VisualBrush.Visual> 
                <Grid> 
                 <Border x:Name="InnerBorder" Margin="1" CornerRadius="5" HorizontalAlignment="Center" 
            Width="50" Background="Transparent" Padding="2" SnapsToDevicePixels="true"/> 
                 <Border x:Name="OuterBorder" Margin="1" CornerRadius="5" HorizontalAlignment="Center" 
            Width="50" Background="Transparent" Padding="2" SnapsToDevicePixels="true"/> 

                </Grid> 
               </VisualBrush.Visual>
