Materia theme made with the Breeze theme for KDE users. Made with the latest breeze and looks great. I like to use these themes made with the breeze theme in KDE so i don't have to install entire gtk themes and these are made for KDE so they work probably better in KDE than regular gtk themes would anyways. Enjoy
If I remember correctly you have to install the Materia chrome extension anyways to get full Materia theme in the browser and this way in KDE you do not have to do that. Install your Materia theme and then install this and you have full setup.
Thanks to the maker of Materia theme for inspiring me to make this. I will admit the first one I made was not complete but this one is perfect so if you use the Materia theme then try this to go with it in KDE Plasma.
You can find the Materia KDE theme here:
I use the Newaita icons and they are here.
