DropShadowEffect Color binding not working

I'd like to bind one of the viewmodel's properties to the Color of a DropShadowEffect. I have tried like a thousand variations but none of them seemed to work.

The style:

<Style TargetType="{x:Type Image}" x:Key="CentralImageStyle">
    <Style.Triggers>
        <Trigger Property="IsMouseOver" Value="True">
            <Setter Property="Effect">
                <Setter.Value>
                    <DropShadowEffect ShadowDepth="0" 
                    Color="{Binding Path=DataContext.CurrentPlayer.Character, Converter={StaticResource CharacterColorConverter},
                        RelativeSource={RelativeSource AncestorType={x:Type Window}}}" 
                    Opacity="1" BlurRadius="50"/>
                </Setter.Value>
            </Setter>
        </Trigger>
    </Style.Triggers>
</Style>

The Control:

<Image Source="{Binding CurrentPlayer.BackImageSource}"
       Style="{DynamicResource ResourceKey=CentralImageStyle}">

and the converter:

switch ((string)value)
{
    case "char1":
        return new SolidColorBrush(Colors.WhiteSmoke);
    case "char2":
        return new SolidColorBrush(Colors.Red);
    default:
        return new SolidColorBrush(Colors.White);
}

My problem is that the color of the DropShadowEffect is black. That kinda means that the converter isn't used.

You're binding to the Color property, but the converter is returning Brushes. Remove the SolidColorBrush's from the converter and just return Colors.WhiteSmoke, Colors.Red, etc...
