How to change foreground of WPF DataGridCell depending on background?

I want to change the color of the foreground of a DataGridCell in a DataGrid when the background is anything but white. So I wrote this xaml:

<Style TargetType="{x:Type DataGridCell}">
    <Setter Property="Foreground"
            Value="White" />
    <Style.Triggers>
        <DataTrigger Binding="{Binding Background, RelativeSource={RelativeSource Self}}"
                     Value="Transparent">
            <Setter Property="Foreground"
                    Value="Black" />
         </DataTrigger>
     </Style.Triggers>
</Style>

Using a converter to test the input and binding, I can see the correct values being generated by the binding. However, the setter does not appear to fire.

edit1: I am setting the cell background color via a converter

edit2: Actually, the background of the textblock of the datagridcell is being set via a converter

I set the background of the TextBlock inside the DataGridCell via a converter. So the background of the DataGridCell isn't actually being changed, which is what I bound to.
