This would be fairly rough to implement in the current Windows Forms framework. Interestingly, .NET 9 adds experimental support for dark mode in Windows Forms, so if/when I upgrade from .NET Framework to .NET (Core), this will be effectively free. However, I should be clear that I am not in a rush to upgrade because it will remove support for older Windows versions.
