Color is an important tool for creating the impression of space in a room. When decorating a small room it is good to use pastel or neutral colors. Blues and greens work especially well to create an open and airy feeling. Again, landscape images or window pieces are great to use in a small area in order to create a sense of depth and expansion of the room. A piece featuring a window scene looking out into the far off horizon is an excellent choice to make your small room seem larger instantly.
