default color-scheme?

Hi, I am working on a new distro, I am the maintainer of KDE, everything 
I got is working just fine, great.. but one thing..
I am trying to change the default color-scheme by default... but when I 
put the livecd together and even when I install
it just ignores the setting and installs into the user direcory ~/.kde 
space another config file I have never wrote..
in my case is kdeglobals I am adding:
[KDE]
colorScheme=Mytheme.kcsrc

but it just ignores it.. I have to manually do it from the gui and of 
course this is not what I need, I need this change globally so any new user
and the livecd gets those colours..

before I decided to come here for help I google the hell out of me, but 
is all GUI related.. I have not found a way to do it from the shell and 
make it system default.
so if I wipe ~/.kde  the new ~/.kde comes with *my* defaults.

Thanks
Chris Fernandez.
