American conceptual artist Tauba Auerbach has created a small run of complete RGB books: that is, a cube-shaped hardback of digital offset prints made up of every possible variation of the red, green and blue colour model. On display at the Museum of Modern Art, New York, the books - worth, if one was to personally attempt to print an edition - in the millions, given the cost of ink - challenge our perception with their bridge between abstraction and graphics. Read it and weep.
