an establishment's license will specify Blue or Red. It can't be both. A restaurant cannot have a blue sign out front, and a red sign at the bar for example. For a CHL, Blue sign, carry away.

There are some unusual places where a Red sign does apply, even tho the venue may appear to be Blue, such as at a Concert Hall, where a concession vendor sells alcohol, but is not part of the concert hall company. This will still make the entire concert hall red.
