Button Settings Mahapps.MetroWindow Close

I am using Mahapps.MetroWindow ( http://mahapps.com/ ) to create the look of my applications, and right now I'm looking for the right way to customize the look of the X / Close button. By default, MetroWindow applies an individual style to all three teams. I would like either a match with Windows when the Close button was red or the mouse turned red.

What I found so far was that I can set the attribute WindowCloseButtonStylein a custom style. I did it like this:

<controls:MetroWindow x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
    Title="MainWindow" 
    Height="350" 
    Width="525"
    WindowCloseButtonStyle="{DynamicResource RedCloseWindowButtonStyle}">
...

In a separate XAML file, I have a style defined as

<Style x:Key="RedCloseWindowButtonStyle"
       TargetType="{x:Type Button}"
       BasedOn="{StaticResource MetroBaseWindowButtonStyle}">
    <Setter Property="XXX"
               Value="XXX" />
</Style>

, XXX . Windows, : ? ? , , ?
