Tan is flooring, white is walls. thats a entryway or breezeway or whatever going from the living room to dining roomI like the filler, looks great.
Is this a floor, or wall, that we are seeing?
If it's a floor, that molding piece, is going to be a trip hazard, and any wheeled thing ( wheelchair, desk chair, serving cart, stroller, etc.), is going to have problems getting over it.
