The example building was painted tuscan oxide red, which is a good brick color. This red is dark enough to use to paint the interior as well. After painting the interior, paint the entire exterior, including the roof, your brick color to ensure the building has an even base color coating. When you look at any structure, you see the paint. The quality and detail of the paint job makes the difference between a toy building and a scale structure.
Brickwork is enhanced by additional attention to detail.
Brick masons add texture to brickwork by laying a contrasting or darker color of brick in random or carefully-planned patterns, especially on the front of buildings. This is duplicated by brushing on a contrasting color paint on individual bricks or coloring them with a fine-point art marker, such as a Berol Prismacolor marker. The Berol mahogany red color is a good contrast to the tuscan oxide red base brick color. Mortar is an essential detail for brick buildings. It makes the brick detail stand out.
