Nevermind, I figured it out. The theme didn’t attempt to change the original colour in the first place!
I’m seeing a few buttons that use the lighter gray background where the font colour conflicts and you can’t actually see the text - examples below from the automations page and one of my components. I’m not very savvy with the theme code - can someone point me in the right direction of resolving this?
Did you resolved that? I have the same issue.
I never did resolve it, no. Unfortunately I just don’t seem technical enough to figure this one out on my own with the theme code and after two months without an answer here I’m feeling there isn’t much interest from the crowd either lol
I also have this issue 
Why do my cards have a much rounder corner than all the screenshots I see for this theme?
Probably because of the frontend change introduced in HA 2022.11 - one of the discussions is here: 2022.11: Card borders
Guys, solution is not so hard.
Just comment out in the theme yaml this line:
primary-color: 'var(--text-color)'
Then restart HASS and Ctrl+F5 in browser to force reload of styles.
Thx, I will test and apply the fix to the repo.
