Почему отсутствует цвет текста в TextBox?

Разметка

TextBlock Margin="10 0 0 0">Логин</TextBlock>
            
            <TextBox Margin="0 10 0 0"   Name="tBLogin"></TextBox>
            <TextBlock HorizontalAlignment="Right" Margin="0 0 20 0">
                <TextBlock.Style>
                    <Style TargetType="TextBlock">
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding Text.Length, ElementName=tBLogin}" Value="30">
                                <Setter Property="Foreground" Value="Red"/>
                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </TextBlock.Style>
                    <Run Text="{Binding Text.Length, ElementName=tBLogin, Mode=OneWay}"/>/<Run Text="{Binding MaxLength, ElementName=tBLogin}"/>
            </TextBlock>

                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}"
