Painted Bricks Or Natural Color

I made a visit through St Paul's East Side Neighborhood and drove past this building that caught my eye. The building has been refurbished in someway, but I'm curious if the red brick is painted or is that the natural color of it? Despite the sign that reads 'The Strip Club' I can assure you, this is a restaurant that a friend of mine has suggested to eat at. I will stop in there soon, but today's stop was only for a quick photo and to find the exact location.
