color scheme, exclude applications

[Dj YB]

hello,

I have this little problem, I like a specific color scheme but unfortunately 
it's not suitable for all applications.
for example Kmail and Kontact in general looks great with it but OpenOffice apps 
are unusable, can't see a thing.
so my question is if and how can I exclude an application from the color 
scheme or perhaps apply to it specifically a different color scheme.

thanks,
YB.
