Living Wall meets kitchen/dining wall at 45 degree angle. At this time, I have two different grey paint colors on the walls, but not sure if is a design NO NO. No trim to separate rooms, just a header above opening between the two rooms. It's almost open floor plan for the living and eating area that is part of the kitchen. Here's what I have now. Should I paint the same color for a better flow from one room to the other? Treat it as all one room?
