Humanity Inspired theme made by me starting by original file of Humanity Icons Theme. This theme must be placed in ~/.purple/themes/, after this open pidgin (2.6.x Version, you can try by the repository that I'm advertising [link]
!?content=111746 ) and select the theme by preference menu.
All icon are now SVG and all XML file are created for fit at any resolution (from 11x11 to 48x48).
Totally New Theme. Better fit and fixed major issues.
