foreground color wont be changed in controlTemplate

I am using WPF. Please look at comment related to Foreground in code. When the textbox gets focused, the font should be changed to white but it is not working. Why?

 <ControlTemplate TargetType="{x:Type TextBox}">
                <Border x:Name="bg" BorderBrush="#FFDCDCC9" Background="#FFDCDCC9" BorderThickness="1">
                    <ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
                </Border>
                <ControlTemplate.Triggers>

                    <Trigger  Property="IsMouseOver" Value="True">
                        <Setter  Property="BorderBrush" TargetName="bg" Value="#FFEC94C0"/>
                        <Setter  Property="Background" TargetName="bg" Value="#FFEC94C0"/>
                        <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                        <Setter Property="Cursor" Value="Hand"/>
                    </Trigger>

                    <Trigger Property="IsFocused" Value="True" >
                        <Setter Property="BorderBrush" TargetName="bg" Value="#FFB5266E"/>
                        <Setter  Property="Background" TargetName="bg" Value="#FFEC94C0"/>
                        <!-- foreground is invalid --> 
                        <Setter  Property="Foreground" TargetName="bg" Value="white"/>
                        <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                        <Setter Property="Cursor" Value="Hand"/>
                    </Trigger>

                </ControlTemplate.Triggers>
            </ControlTemplate>

Border does not have a foreground. Remove TargetName from the equation... I believe it will work then. It should look like below (also if this is a resource itt will need a key). This worked fine my end.

<ControlTemplate x:Key="a" TargetType="{x:Type TextBox}">
        <Border x:Name="bg" BorderBrush="#FFDCDCC9" Background="#FFDCDCC9" BorderThickness="1">
            <ScrollViewer x:Name="PART_ContentHost" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
        </Border>
        <ControlTemplate.Triggers>

            <Trigger  Property="IsMouseOver" Value="True">
                <Setter  Property="BorderBrush" TargetName="bg" Value="#FFEC94C0"/>
                <Setter  Property="Background" TargetName="bg" Value="#FFEC94C0"/>
                <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                <Setter Property="Cursor" Value="Hand"/>
            </Trigger>

            <Trigger Property="IsFocused" Value="True" >
                <Setter Property="BorderBrush" TargetName="bg" Value="#FFB5266E"/>
                <Setter  Property="Background" TargetName="bg" Value="#FFEC94C0"/>
                <!-- foreground is invalid -->
                <Setter  Property="Foreground"  Value="white"/>
                <Setter Property="BorderThickness" TargetName="bg" Value="2"/>
                <Setter Property="Cursor" Value="Hand"/>
            </Trigger>

        </ControlTemplate.Triggers>
    </ControlTemplate>
