Not all of the Bction installation was in colour. A lot of the artists used black and white or were monochromatic. Some used tape on the windows, spray paint on the walls, marker on white walls, black-and-white photos in frames, or pencil on washi paper. Some used minimal colour with their plaster or mixed media; some left the floor colour is to focus on the sensation of walking on its uneven surface. Some people were dressed in colourful outfits, but many were dressed in black or white.
