Styles with Trigger on IsMouseOver still shows the winfows blue color

Question

Right now I'm trying to use styles in my very new wpf solution.

 

I have problems with the Trigger IsMouseOver background color. Even when using another background color it still shows Windows blue on mouse over. Do I have to set another property for the mouse over blue color?

 

Can anyone tell me, why I can make the style Bold but not cann't change the windows normal blue color on mouseover a button?

 

I have attached the solution

 

But here is the code first my app.xaml file

And here is my
