I want to change the block title background color to blub and the block title text color to white.
If i use the command
%\setbeamercolor{block title}{fg=white,bg=blub}
The titel is good, however the block content color is also changed i do not understand why and how can i fix this. I want to keep the old colors, which i think is blub2
