This work, belonging to the first year exhibition "L'avanguardia americana" of Casa Morra program, as Kaprow pointed out, “… must be painted in different colours by the visitors each day: white, red, orange, yellow, green, blue, purple, and black, repeating this sequence every eight days. Those who wish to take part will find suitable brushes, rollers, a ladder and something to protect their clothing. Feel free to take part in this process!”
