hello again, i've update white carbon theme. now it can be customized with theme customizer.
thanks iivil to have explained me the problems in this theme. now i've added also colors.config in deb package. i've also removed that line referred to your theme :P
btw white carbon worked great also without colors.config, because, for what i know, font colors are managed by gtkrc file...so in past i've deleted colors.config because i thought it was useless...

for othere themes i'll have a look to fonts and colors as suggested by you users.

stay tuned!
