A head-up display device is provided in a vehicle together with a headlamp. The head-up display device includes a light source, a control unit, and a projection unit. The light source emits white light whose correlated color temperature is changeable. The control unit adjusts the correlated color temperature of the white light emitted from the light source. The projection unit forms image light by the white light emitted from the light source. The projection unit projects the image light onto a projection target member disposed in front of a driver of the vehicle, thereby displaying a virtual image superimposed on a landscape for the driver. The control unit adjusts the correlated color temperature of the white light emitted from the light source in accordance with a correlated color temperature of irradiation light emitted from the headlamp.
