Setting the foreground[text] color of the button in a resource dictionary

I am defining a button style in Buttons.xaml file. Can you please tell me how to set the foreground property of the button? I need to use a gradient as foreground property. Code is as below. Right now i am setting the gradient within the button tag.

 <Style x:Key="ButtonCancel" TargetType="{x:Type Button}">

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <ControlTemplate.Resources>
                        <Storyboard x:Key="Storyboard1">

                                <SplineDoubleKeyFrame KeyTime="00:00:00.1000000" Value="0.68"/>

 <Button Style="{DynamicResource ButtonCancel}" Click="btnCancel_Clicked" FontFamily="Tw Cen MT" FontSize="18" FontWeight="Bold" Width="144" Name="btnCancel"
                HorizontalAlignment="Right" Grid.Row="1"  Grid.Column="1" Margin="0,73.5,0,55.5">
            <Button.OpacityMask>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#9B000000" Offset="0"/>
                    <GradientStop Color="White" Offset="1"/>
                </LinearGradientBrush>
            </Button.OpacityMask>

        </Button>

In the style? If so use a setter:

<Style x:Key="ButtonCancel" TargetType="{x:Type Button}">
     <Setter Property="Foreground">
         <Setter.Value>
             <!-- LinearGradientBrush here -->
         </Setter.Value>      
     </Setter>
     <!-- ........ -->
</Style>
