A comment below suggests adding more Application Icons. However, to do this, I must know the name of the icon, as it is listed in your /usr/share/icons/hicolor/48x48 or other size directory. Some app icons end up elsewhere. If you cannot find it, it is probably in its own folder. For example, Conky-Manager has its icon in /usr/share/conky-manager/pixmaps.
I am not willing to install a great deal of software onto my computer (then have to clean it off later) just to learn the names of icons. If you have a request, please submit the full icon name along with what you would like an icon of.----
----UPDATE--- Added Chrome and Opera icons per the request made below.
----UPDATE---Added Green Torque Icon set as per the request below--- Please Be Sure To SELECT THE COLOR SET YOU WANT TO THE RIGHT>>>----
Torque Icon set:
This is a full set with the above photo a general preview.
The original blue can be found here: https://www.pling.com/p/1348024/
along with the description.
You will notice some subtle differences (if you try both sets) between this set and the original. Some icons need a slight change to adapt to a color change. Also, some were easier to just make from fresh than to re-color the original.
extract contents to your /usr/share/icons folder or to ~ /.icons
