Changing colors on forum

[revtec]

Hello,

I'm trying to change the color of the forum to match my website.  I can't find where to change the code. 

My forum addy is  hxxp:www.revtecmotorsports.com/forum/index.php [nonactive]

I want to change the gray border around the News box, Info Center, etc to black.

I would also need to change the Title Revtec Tunerz (this is where the tree is) to a different color like white.

I'm new to this, so I would appreciate some help!  Thanks!
