An expanded icon pack for the GNOME Desktop (mainly), based on the Adwaita Icon Theme and inspired by Ubuntu's Yaru theme suite, customized to meet a mixture of both themes' design guidelines (hence the name Adwaitaru = Adwaita + Yaru), attempting to bring together the best of both worlds. Built largely upon the graphic work of GNOME's Adwaita designers, Canonical's Yaru design team, GNOME Circle apps' developers, and some assets taken from the MoreWaita icon theme by Paulo Fino.
Adwaitaru shows a clear preference for Adwaita, but with Yaru's finesse and attention to detail. Though it could be said this is a mixture of Adwaita's scalable icons with Yaru's symbolic icons, the icon pack tries to deepen into what works best from both themes, fine-tunes symbols to match styles, and improves visual accessibility in general through tuning small details and enhancing color contrast ratios. Adwaitaru widens the icon range for apps and file mime-types, attempts to satisfy both light and dark themes indistinctly, and provides custom color folder themes (according to Ubuntu's accent colors).
This has been mainly a hobbyist's personal work. A lot of tinkering has been done to adapt most of the icons to be displayed as best and clean as possible.
