If Blue Bell is smart, they will use this new wave of attention to their brand, and quickly come up with a new flavor that this family would like. Heads have been turned in their direction, but just for a while.
Maybe shoot a YouTube video or commericial showing this family trying the new flavor out, but only if the kids like the taste.
I would not remove the Great Divide, though.
How about "Transparent" ? (get it ? Trans Parent)
If they mix the chocolate and vanilla, and throw in a little mocha they could call it Mudslide.
No one could find anything racist in that.
