1. A lighting device for creating dynamic atmospheres, said lighting device comprising: a light source adapted to operate in a plurality of color states, the light source emitting differing colors for each color state; a controller for controlling the color state of the light source, the controller comprising a random generator implementing a stochastic model to provide a transition between a previous and a subsequent color state; wherein the controller is adapted to provide the transition based on probabilistic output provided by the random generator, the probabilistic output depending on the previous color state.
