There are a very well made icon theme named .nitrux. That is packed for generic GTK and a specific KDE version. The upstream seems very receptive. Please consider adding on portage tree. There are a old ebuild on ephemeral ovelay, but that seems to be only for GTK version: http://gpo.zugaina.org/x11-themes/nitrux-icon-theme Thank you! Reproducible: Always
The theme was killed by Nitrux.
