Where can I download themes for Visual Studio 2019?

My understanding is that there are currently many ways to add new color themes in Visual Studio 2019, but none that really fits my needs:

• The extension Color Themes for Visual Studio installs new themes to chose in the native options menu,
• The extension Color Theme Editor for Visual Studio 2019 installs a gui to chose and install themes,
• The marketplace that contains a category Themes but the selection is scarce compared to the VS Code themes marketplace,
• I also stumbled upon Dainty which seems nice but a Group Policy won't let me build themes on my machine, plus I'd rather not use third party software (and install node + yarn) since Visual Studio has a native support.

So, what I am looking for is a way to easily find themes so I don't have to create or build one myself.

More specifically, I'd like to install an equivalent of the theme Winter is Coming Light found in the VS Code marketplace which I cannot use directly in Visual Studio 2019, since they use different theme formats (.vstheme is XML versus JSON for VSCode) and, by extension, any way to browse through a selection of themes as rich as the one we can find on VS Code.

There is a themes converter that can take any Visual Studio Code theme and bring it to Visual Studio 2022:

It's not just click and install, you actually need to use it with Visual Studio to prepare a VSIX extension, but it's just a few minutes of work and it's well documented.
