a question about fonts and colors

[A Soare]

Can somebody give me a idea how can I solve this problem (and old problem):

I want that at all the times when I switch to a buffer with a given name (name 
set in .emacs) the frame of that buffer to change in the buffer color that I 
want and also the frame's font changes (color and font assiciated in .emacs 
with a buffer name).

Thanks in advance.
