Currently, the default icon theme takes the fallback if the desktop environment is not KDE or Unity. Better we change this to Gnome and use Elementary instead of Breeze. Ideally, we also remove the no longer supported DE tde and kde.
Patch at https://gerrit.libreoffice.org/#/c/52117/
Not really following this, as the fallback is tango when its not KDE or MacOS, but using elementary over tango isnt good, as tango is based on gnome's default Adwaita. When you say 'default icon theme for gnome based DEs', do you mean gtk based DEs, as we have many gtk based DEs that arent gnome?
With the recent patch for bug 90194 it's Colibre which is taken as fallback theme instead of Tango. And since Tango is not maintained we should aim to completely get rid of it. Elementary is the better option for the different gnome variants, including gtk2 and gtk3 (at the moment we have defined only Unity in the fallback strategy).
While I agree with Jay that Tango is the best fit for GNOME, we should take into account that the elementary theme was started back in 2007 (at DeviantArt!) as a variation on GNOME, heavily inspired by the Tango guidelines — so it’s also fitting for GNOME, IMHO. Funnily enough, some members of the upstream elementary icon team have contributed to Adwaita, so both themes are more similar than dissimilar.
From a maintainer point of view you can choose elementary. If someone will maintain tango than I would choose tango.
Do we have svg versions for tango or elementary?
We have SVG versions for elementary but only a few icons in tango are SVG.
I would definitely choose Elementary. It follows Gnome's and Elementary guidelines, and looks more modern than Tango.
Elementary is full svg which may help when LO will switch to svg (hope soon)
