Accent color when Windows determines the accent color itself

Describe the bug

Windows 10 has an option:

“Automatically select an accent color from my background”.

This will select an accent color based on the background. But the color that MahApps / ControlzEx then sets is unfortunately not the same one that Windows then uses 😕

Maybe the error is also in “ControlzEx”. But since I only used MahApps I post it here 😃

Steps to reproduce

• create a project (.net 5 for example)
• include MahApps.Metro
• Overwrite “OnStartup” in the App.xaml.cs" and add the following:

ControlzEx.Theming.ThemeManager.Current.ThemeSyncMode = ControlzEx.Theming.ThemeSyncMode.SyncAll;
ControlzEx.Theming.ThemeManager.Current.SyncTheme();

• In Windows, set the “Automatically select an accent color from my background” setting.

• Compare accent colors

Expected behavior

That the accent color MahApps.Metro uses is the same as in Windows.

Actual behavior

The accent color MahApps.Metro uses is not the same as in Windows. (Usually a little darker than the current color)

Environment

MahApps.Metro version: v2.4.7
Windows build number: Win10 21H1 [Version 119043.1151]
Visual Studio: 2019 16.10.4
Target Framework: .Net Core 5.0 (but also happens in other versions)

@punker76 Could you transfer this issue to ControlzEx? I can’t see the transfer button… Will fix it there next week.
