[WPF] Color variant not rendering

[KeyMetricSoft]

I'm using this library in several WPF apps, and I've noticed that setting IconVariant to "Color" doesn't seem to change their appearance. Icons will often behave as though I'd used the "Filled" option instead, or in some cases not appear at all.

This occurs regardless of whether I set the Foreground attribute. I've also tried using both SymbolIcon and FluentIcon, but they seem to behave the same way (metrics notwithstanding).

Perhaps I'm misunderstanding something. Is this supported in WPF?

I'm using the latest version of the FluentIcons library available through nuget.

Hi. are you using a Windows version that supports COLRv1?

Hello, and thanks for sharing this library.

Yes, I'm using the current Windows 11 release.

I tested and it turns out that WPF just does not support COLRv0/v1. The best I could do is to make COLRv0 work with something like https://github.com/samhocevar/emoji.wpf/blob/main/Emoji.Wpf/Internal/OpenTypeFont.cs but it will not support gradients still, making the rendering results possibly ugly. I would prefer to leave it as is and wait for Microsoft, or migrate to SVG which will be an epic project.

Thanks for taking the time to look at it, and for answering my inquiry.
