            <Setter.Value>
                <ControlTemplate TargetType="Label">
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Foreground" Value="{StaticResource mouseOverColor}" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                    <ContentPresenter />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

Answer 1

You don't need to override template at all. This can be achieved with following style only:

<SolidColorBrush x:Key="mouseOverColor" Color="Gold" />
<Style TargetType="Label" x:Key="mouseOverStyle">
   <Style.Triggers>
       <Trigger Property="IsMouseOver" Value="True">
          <Setter Property="Foreground" Value="{StaticResource mouseOverColor}"/>
       </Trigger>
   </Style.Triggers>
</Style>

Your trigger won't work in case you are specifying default value of Foreground on your label.

Won't work for this label:

<Label Content="sjdfjfddjfjdfs"
       Style="{StaticResource mouseOverStyle}" Foreground="Green"/>

However, will work for this label:

<Label Content="sjdfjfddjfjdfs" Style="{StaticResource mouseOverStyle}"/>

Even your style will work but make sure you are not setting local value for Foreground DP. This is because of Dependency Property Precedence order where local value holds higher precedence than setter values of style.

Answer 2

Have you tried changing the Value for the Foreground property in your Setter ?

eg

<Setter Property="Foreground" Value="White" />

Or defining a Brush of your desired color and using that? eg

<SolidColorBrush x:Key="myColor" Color="White" />

    <Setter Property="Foreground" Value="{StaticResource myColor}" />

Rohit's answer is much simpler/more sensible if you're just after the label color change (rather than doing anything with the ControlTemplate .
