Silverlight 4 Front Color

Question

I am trying to animate a hyperlink foreground color when a MouseOver user controls. I created my own style in which I want to animate the foreground color. Foreground color set this way

<Setter Property="Foreground" Value="#FF73A9D8"/>

In the visualStateManager section, I have the following item for color animation

<ColorAnimation Duration="0:0:0.5" 
              Storyboard.TargetName="contentPresenter" 
              Storyboard.TargetProperty="(Control.Foreground).(SolidColorBrush.Color)" 
              To="Black" />

The problem is that I cannot figure out what the value of Storyboard.TargetName should be.

The text is set in a ContentPresenter control that does not have a Foreground property.

You're right. Cannot hang animation inside control template.
