How to customize color schemes in WinUI 3? (e.g., modifying accent colors and background colors)

[Rwagsu]

I want to change the color scheme for my WinUI 3 application, but I encountered issues when modifying the resource dictionary:
Directly editing the resource dictionary does not work because these controls seem to have their own resource dictionaries for color settings. Modifying them directly would require significant effort and could easily break functionality, especially since my app supports extensions.
Are there other methods to apply a custom color scheme? Thank you.

Earlier, I checked this library, and I think it doesn’t align with my requirements 😥 Since this library appears to be built around data binding, while my application is extensible, implying that new modules or features might be integrated dynamically. Still, thank you for sharing the repository—appreciate it! 😋

There is an older project (https://github.com/microsoft/fluent-xaml-theme-editor) that allowed you define a new color scheme and export it as a resource dictionary which overrides the base colors used in WinUI application. It looks like it's no longer supported, and the output isn't perfect but it does get you most of the way there.
