Theme are related to Desktop Environnement/Window Manager (KDE, Gnome, BSPWM,...) not distro
So as long as the theme is available for yours, you can get it on Debian or Arch it doesn't matter 😉
Edit : yum13241 makes a good point
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It should work if the theme doesn't use features from newer GTK/Qt versions.

Looks similar to dracula. Might be an alternative you can live with?
