As soon as the mouse moves off of the label, subsequent to the Event.Trigger having changed it to Red, (See pasted markup, below.) the foreground returns to PowderBlue.

How would I get the default of PowderBlue, but also get the Red to persist, subsequent to MouseUp, and the cursor moving off the label?

Thank you in advance, for your assistance.

<Style x:Key="Style" TargetType="{x:Type Label}">
<Setter Property="Foreground" Value="PowderBlue"/>


<EventTrigger RoutedEvent="MouseUp" >
<BeginStoryboard >
<Storyboard >
<ColorAnimation Storyboard.TargetProperty="(Foreground).Color" To="Red" Duration="0:0:1" AutoReverse="False" FillBehavior="HoldEnd" />
