The conventional idea is that the walls of a small space should be coated with a shade of white in order to make it look larger than it actually is. This idea is quite outdated as small rooms that have walls painted white look boring and dingy. You should choose such a color that would be complementary to the furniture of the room. You should get the walls painted with colors that will generate warmth and add to the look of the dining room.
Nice furniture with glass covered shelves carrying the crockery would go very nice by a large table with comfortable chairs. Try to put nice light fixtures to create a comfortable and a cozy atmosphere for your dining room. You could arrange flowers over the dining table in order to get the warm welcoming feel. The dining room is a place where the family can reunite so keep in mind that the place has to be tidy and clean so that everyone can have a good time with each other.
