Neither can I without breeze(seriously, my home heater is attached to an aeolic energy generator, without it, I would freeze to death)
That's the one, Underworld paired with Bali10050 for coloring is the best KDE dark mode setup in my book.
You'll have to excuse my ignorance, I'm just not to sure, isn't changing to Underworld and Bali altering the GTK theme? I use Breeze Dark, then Underworld, Bali's Black, and still playing with different icons. Currently Griffin Ghost is my choice, plus the high contrast cursor.
Oh, I see, ya that's a bit above my pay grade. I just got a setup which looks clean and stuck with it lol. But let me know what your think of the layout!
I think that's just in the settings. Select edit profile in the settings menu and then to change the text color, you'll find many options under the appearance tab, hope this helps!
