[REQUEST] crystal shape edit

Hey guys, bit of a noob to the forums here so don't be hating.. :p
Anyways, i recently downloaded the crystal shape theme ( by mmooo or something like that).. Anyways, i really like the theme apart from one major put off.. The bbm menu and chat logs colour scheme and text colour has changed drastically, i was wondering if anyone would be able to edit this theme in order to change it back to the default bbm kind of stuff.. i dunno about any legal issues with this but ya noe..
