A head-up display includes at least three light sources, each one arranged to emit light with a basic color different from the basic color of the other light sources, a digital micro mirror device including an array of micro mirrors, wherein the light of the light sources is directed onto the digital micro mirror device, at least one combiner for displaying an image, and at least one control unit for multiplexing the light sources so as to sequentially emit light thus creating a field sequential color system and for controlling the digital micro mirror device so as to selectively rotate the micro mirrors between an on state, where the light from the light sources is reflected into an optical path towards the combiner, and an off state, where the light is reflected away from that optical path. A method for operating the head-up display is also disclosed.
