The special design characteristic of this theme is the use of drawers instead of folders, and although this element has been limited in the latest version of the icon set, you will still find drawers in some cases.
The good thing is the plethora of icons. I tested many applications that I use and found that almost everything was available and modestly sightlinessed by My-Humanity. Take this 0 A.D. icon shown in the following screenshot for example.
To install and use this icon set in your system, you should download the compressed file and unzip it under /home/.icons (create this folder if it doesn’t exist). You may then choose the set from Gnome tweak tool. No restarting should be required if everything was done correctly. For more details, check our comprehensive guide on how to theme Gnome 3.
