Mobile Version Text Colour

Greetings.

I have redone our whole forum design today, and my members drew my attention to the fact that the mobile version of the site basically has black text on a very dark background.
This is strange because we have no black text on the forum at all.

I tried locating the mobile version text colour option and other things, but I have so far failed. Does anyone know how to set the colours right there?

(PS.: Does anyone know a nice font like Copperplate Gothic that has both upper- and lowercase letters by any chance?)

Hi there, what color are you looking to set it too?

Some light gray would be fine, i guess.
