Imagine a home with an open floor plan. When you first think of creating a color scheme for the space, what comes to mind? Color schemes in interior design are simply the organization and choices of colors placed throughout a space. These colors and their combinations can influence how a person experiences a room. The color scheme can create a mood, enhance a particular style, and bring cohesion to disparate things in a single area. Often a color scheme is used to create a visual relationship between two or more adjacent areas or rooms.
