Answer 1

Starting with .NET Core 3.0 it is also possible to call UWP APIs from non UWP apps with the help of Microsoft.Windows.SDK.Contracts package.

So we can use UWP API to get accent color from .NET Core console app using:

var uiSettings = new UISettings();
var accentColor = uiSettings.GetColorValue(UIColorType.Accent);

The returned color is of type Windows.UI.Color, but can easily converted into for example System.Drawing.Color

Color.FromArgb(accentColor.A, accentColor.R, accentColor.G, accentColor.B);

Answer 2

HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM\ - Stores all decoration colors. So if app launched with rights to HKEY_CURRENT_USER you can read or change "AccentColor" property (and others in directory) or change the color code in hexadecimal notation on your own.

To get access to windows registry you need to install package: https://www.nuget.org/packages/Microsoft.Windows.Compatibility/
