Yes, I'm think this is a great feature for Emacs. It will make Emacs looks
awesome in some places.

Dimitry, I also found your first replied VS Code's theme screenshot. It looks
great! right.

That's why I hope Emacs can have this too.

I don't know C/C++ programming, but I checked my posted patch's source code,
it's not long. I think it might nor hard to implement in Emacs on Linux. Maybe
other operating system platforms.
