I do not drink much yellow or pink lemonade because if I overdo it my mouth will hurt. I guess it is the acidity in it. I can get away with it in reasonable amounts from time to time. When I do, I always drink pink... I don't even know if it tastes different, I just HAVE to have the pink though.
One thing I have discovered that I can drink excessively without it breaking out my mouth is the Crystal Light Raspberry Lemonade. That is some good stuff.
