Bright splashes of orange and a graphic piece of art balanced against cool, pale blue make me think of the shore. This guest room feels like a perfect landing spot after a day on the beach or strolling the boardwalk.
Oversized art is a nice way to fill wall space without adding visual clutter. Select a piece that ties into your color scheme so the room will feel harmonious. Allposters is one of my favorite websites for sourcing affordable wall art.
