phpBB • Free and Open Source Forum Software

Hello.
I am very new to phpBB. I started a forum which is dedicated to tennis. We are using pro-silver but, in a previous forum (vBulletin based) we had themes that were related to the 4 Grand Slams (USO, Wimbledon, RG, AO).
The problem: I know I can edit the colour.css file for the colors. But, is there a guide to tell me the names of the components for the pages?
As in: So one can go in there and insert the new color code.
If there is a guide, one can manually change the colors and no further problems.
