How to Enlarge Space with Color
Painting walls white, cream, pastels, or cool colors (tinged with blue or green) creates the illusion of more space by reflecting light. Paint trim similar to walls (or use white on trim) to ensure a seamless appearance that visually expands space.
Use a monochromatic scheme to amplify the dimensions of a room. Select furnishings in one color and paint walls and trim to match. Lack of contrast makes a room seem more spacious.
Make walls appear taller by extending wall color onto the ceiling. Create a 6- to 12-inch-wide border of wall color on the entire ceiling perimeter, or wherever walls meet the ceiling.
Vertical and horizontal stripes of alternating color can make a room grand. Although vertical stripes enhance room height by drawing the eye upward, horizontal stripes lure your gaze around the perimeter, making walls seem further away. Use similar light colors for low-contrast stripes, and your room will look even larger.
