Set BorderBrush color with a trigger

I am having difficulty getting the correct syntax in ControlTemplate. Here is the basic information:

<ControlTemplate TargetType="{x:Type foo:bar">
    <Border Name="Bd">  
        <Border.BorderBrush>
            <SolidColorBrush Color="{DynamicResource DefaultBorderBrushLightBrush}" />
        </Border.BorderBrush>
    </Border>

    <ControlTemplate.Triggers>
        <Trigger Property="IsSelected" Value="true">
            <Setter Property="(Border.BorderBrush).(SolidColorBrush.Color)"
                    TargetName="Bd"
                    Value="{DynamicResource PressedBorderDarkColor}"/>
        </Trigger>
    </ControlTemplate.Triggers>
</ControlTemplate

This gives the msg error

Cannot resolve the Color property of the template. Verify that the owner type is a TargetType type, or use the Class.Property syntax to specify a property.

This seems clear enough - I am not correctly specifying the target property. I tried this in several different ways. In particular, I tried

<Setter Property="BorderBrush" TargetName="Bd">
    <Setter.Value>
        <SolidColorBrush Color="{DynamicResource PressedBorderDarkColor}" />
    </Setter.Value>
</Setter>

... and this creates, and, I believe, gives me what I was looking for.

But why can't I set the color of the brush? How can I specify it?
