@ruidovisual Thanks for the explanation, I have figure out how to change the fonts, thanks to you!
I am now playing around with my own light and dark version of the theme. I am using the Color Palettes to achieve this, as I wish to stay away from CSS as much as possible.
I have managed to tweak almost everything except these two elements :
-
The status bar below the post has a special effect in your theme and I am not able to control it with the Color Palette. How do I tweak this using CSS? Which part do I target?
-
The bar on top of all topics in the separate category view stays white no matter what colour I set in the palette
Would be great if you could help me with these 
P.S. This is my Color Palette for your reference :
