They look like a mix of Oxygen and Breeze. And look absolutely beautiful!

Much better than the current Breeze icons which look overly simple and flat.

This is the type of visual overhaul I was talking about.

These icons coupled with a great default wallpaper will make Plasma 6 look awesome!

Thanks to the great work from Ken Vermette who initially created the new icon set, and Niccolò Venerandi, who took over and improved it!
