Do you get $1 chips for a 3/6 game at a casino?

I almost always just buy a rack of white. I usually have more cash in my pocket to reload if I get light. At the cardroom I play at nearly everyone just buys in with white. If someone does dump a few reds on the table it is funny watching people play with them. They almost want to get rid of their reds and will make stupid calls just so they can get their 1 or 2 red chips into the pot.
