Nope. Primary. https://store.kde.org/p/1002483

I see system76 is doing something similar for their PopOS?

It uses a semi-flat design with raised 3D motifs to help give depth to icons.

I remember Noia, they were too 'shiny/glassy' and 'playful' for me. Looked different and funny for a while, but unusable for daily driving. I prefer something more 'serious', unobstrusive, not distracting.

I see someone did a Noia KDE Reloaded in 2019: https://store.kde.org/p/1293856

For shiny things, these did work for me, for a while, or could, if I retried them again:

Faenza https://store.kde.org/p/1012545 ,

Faience https://store.kde.org/p/1012543 ,

Meliae https://store.kde.org/p/1012498 ,

Delft https://store.kde.org/p/1199881 , https://www.opendesktop.org/p/1169579 ,

but I'd rather go to something like Flat Remix instead.

Hedera would look good, too, if not abandoned: https://store.kde.org/p/1207800 / https://gitlab.com/sixsixfive/Hedera-icons

If they were as comprehensive & complete as Breeze I'd go for Retrofukation https://store.kde.org/p/1012499 or IndigoMagic https://store.kde.org/p/1015788 instead.

But they aren't. So Breeze it is, which is bliss...

I'd love the Tango2 icon theme being updated. It was like the old Tango one but slightly more current.
