ToggleButton Style; Override IsEnabled - wpf

Question

Once the ToggleButton is checked, the Button should be set to disabled and the foreground color should change. The following is not working:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ToggleButton Content="Hallo" Margin="113,97,72,46" >
<ToggleButton.Style>
<Style TargetType="{x:Type ToggleButton}">
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="IsEnabled" Value="True"/>
<Setter Property="IsChecked" Value="False"/>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="IsEnabled" Value="False"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="Green"/>
</Trigger>
</Style.Triggers>
</Style>
</ToggleButton.Style>
</ToggleButton>
</Grid>
How can I do this?

The appearance of disabled controls is different across different versions of windows and different Windows account settings etc, this is why it's working for others but not you. Generally speaking you should respect such settings, but if you really are adamant then you'll need to explicitly override the template as demonstrated in this question:
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ToggleButton}">
<Grid Background="{TemplateBinding Background}">
<ContentPresenter x:Name="MyContentPresenter" Content="{TemplateBinding Content}"
HorizontalAlignment="Center"
VerticalAlignment="Center" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
