Greetings,
Royal Z is a black/white icon theme based on Spring and Papirus for Zorin 16 and Zorin 16 Plus. But should work without any problem on other distros as well.
It aims for Black GTK/Gnome-shell themes.
This is an alpha stage release for feedback and requests.
"Royal Z" goes well with the GTK/Gnome-shell theme "Shade of Z", which are available here: Shade of Z - Desktop - pling.com
Download "Royal Z": Royal Z - pling.com
I think the icons looks sweet. What I like best about them is they got rounded edges. But yes, they do also match well. And your desktop background looks like armored plating on something, so thats cool too lol.
Looks good 
An alpha 1 version of Royal Z have been released for testing.
Get it here: Royal Z - pling.com
An alpha 2 version of Royal Z is now available at Github. I finished the mime types icons. That took all day and night.

I really love the transparency of the window. You can see your desktop behind the icons which is cool. And that is one cool cat.
