While he was in Arles, Van Gogh made this painting of his bedroom in the Yellow House. He prepared the room himself with simple furniture and with his own work on the wall. The bright colours were meant to express absolute ‘repose’ or ‘sleep’. Research shows that the strongly contrasting colours we see in the work today are the result of discolouration over the years. The walls and doors, for instance, were originally purple rather than blue.
