Tropical design is a great way to turn any room in your home into a relaxing, casual retreat. Though most designs are used in living room, but it can also applied to dining room. The tropical dining room design pulls inspiration from carvings in island motifs and furniture made from dark or exotic woods. The tropical dining room design also can be decorated with light walls, carved pieces and wooden accents. For the walls, paint all walls with pale colored paint in blue, green or yellow. Paint any trim pieces white. Allow to dry thoroughly.
