all of the colours and would love a 'precise how to tutorial' on the subject. Any one?
AND a very Happy Xmas to you all!

have you looked at the styles available? there is just about any color combination you can imagine already done for prosilver.
also there is colorize it so that you can just move slide bars around until you get what you want.
( I have never been able to figure out how to make it work but others have ).
however, the bottom line is that for prosilver, all of the colors and images are in the colours.css file
you make whatever changes you want to that file and refresh the style components and you are done. if done correctly , it works every time.
spend some time checking out the menu at the top of this page. there is an amazing amount of information about anything you could possibly imagine about phpbb there.
pay particular attention to the knowledge base.
luck,
