The living room interior can be of any theme like contemporary theme, modern theme or traditional theme. It is up to you to set up the theme for the room. Some homeowners intend to reflect their background, values and religious ethics through the interior, if you are one of such people, you can use relics and religious accessories on the walls and in the interior nicely so they can pass the message to others who will come to visit and meet you in your home. The theme should not be over done in the room it can creates a hell of a mess up if you over do the wall painting colors and add too much of the lighting in the area. Try not to over do anything else, it will not garner good results instead it will create a nasty room that will not feel comfortable at all.
