I love this one! I was thinking about migrating to Arch but it’s too much work right now. I wonder if the colors can be tuned to even more red… Managed to modify the theme by using Marble’s script, so now is more in line with the wallpaper
Icon pack: Papirus Dark https://www.gnome-look.org/p/1166289/
Shell theme: Marble Dark Custom Accent https://www.gnome-look.org/p/1977647/

Is part of the marble dark theme. I tweaked the color by using the script they provide to change the accent color to something more in line with the wallpaper. You can also use other colors! Give it a try and let me know if it works
