Finding a color scheme can come from many sources of inspiration. Color boards are fun to make and could help you discover a theme different from what you had originally thought of pursuing.
Below is an image of graffiti art on a brick wall in San Francisco. The use of colors, bold lines, and shadow contrasts with the surface of the wall and an urban energy. A living room concept was developed using the play of colors and materials for a few options that could work in an urban residence.
Another example is taking an image of a setting, landscape, building such as the color board below. Bringing the outdoors inside for this interiors theme involved a strong collection of color, clean lines for the furniture, and a gloss to the finishes to give an image of newness and casual luxury.
