If you want to create a lovely, light marine atmosphere in your home, I recommend that you stick to three colors: white, dark brown and blue in different tones. Red can be used as an accent color, and if you really want to stick out use orange. By balancing the proportions of white and dark brown you can change the appearance of the room. Then add different marine interior details. They must have a real marine look, no mainstream stuff from your local interior shop. I have collected some favorites below.
Example 1: white walls, white painted floor/light ship deck, white vertical wooden panel, marine inspired beige or blue wallpaper, and finally a white sofa and armchair. Coffee table and side board can be dark brown, pillows mainly blue maybe an occasional red.
Example 2: white walls, white/blue sofa and armchair, dark brown floor, coffee table and sideboard.
