I actually don't do that. First of all if i was looking for a bahu the last thing i would be concerned about would be if she was 'kaali' or 'gori'
I also take care in how I speak about other races. If we ourselves don't change and carry on with this offensive, kaala or gora thing then our kids will follow us. I would never ever want to hear these things from my children.
I am talking about norms ...... of course there are exceptions ....
