figuring out which theme am I running under Debian-mate?

Question

I have 2 desktops, GNOME and MATE.

As far as I know the GNOME 3 theme lives under [~/.config/gtk-3.0

On right-click > Change Desktop background > Appearances and Themes > It's menta with some customizations which is part of mate-themes and it's at 3.20.7-1 on Debian unstable/sid. This shows Menta look with some modifications. Menta is both a 2.0 and 3.0 look/theme.

 [/usr/share/themes/Menta] 
└─[$] ls                                                         
cinnamon  emerald  gtk-2.0  gtk-3.0  index.theme  metacity-1  README  unity  xfwm4 

[~/.config/gtk-3.0]

[$] cat settings.ini

Look forward to know which theme am I using.

The easiest thing to do is to simply use the gui.

On your panel go to System>Appearance and click on that.

First thing to come up should be the tool for setting the theme and so forth. The one in current use should be highlighted in the upper right hand corner of that tool.

There you can customize the look and feel of your Mate desktop. Have fun exploring.
