Yeah, unfortunately there's no inverse mouse cursor theme. I loved it on windows as well. What I'm using now is this "Hackneyed high contrast cursors" theme, the green one to be specific, and I absolutely love it.
Example.
I don't actually know, but I assume mouse themes are universal? Or does KDE mouse themes now work with Cinnamon?
I read that there's an extension for Cinnamon that does the same, although I also saw a bug report that it might be broken, idk. Worth a shot. Here's how to enable it.In KDE Plasma there's also a setting where you can shake your cursor to make it bigger, although I don't feel like I need it.
