How to change forum font colour

[invitezone]

Hi all,
just a simple question that I think is really easy for experienced users to answer.
I want to find out how to edit the font colours of the forum description.
I know I can manually edit the colours by adding html colour tags around the text I enter as a forum description, but I want to know how I can change the default for the entire VB skin I have installed. I have a dark background skin with black text, so obviously it is hard to see.

I also have ipbproarcade installed and have the same issue with the colour of the txt on that, so I am thinking there must be something I can change that will affect globally the whole skin.

Thanks for looking everyone.
If you need more info please ask as I dont know what im doing just yet, so maybe I have missed some info you may need to help me.
