A vehicular head-up display system comprises a display panel, a semi-transmissive plate, a chromaticity acquisition unit, and a controller. The display panel has a display surface for displaying an image. The semi-transmissive plate is configured to reflect display light from the display surface and guide the light to a certain space. The chromaticity acquisition unit is configured to acquire the chromaticity of a background superimposed on a virtual image of the display surface, wherein the virtual image is to be visually recognized by an operator positioned in the certain space. The controller is configured to calculate the chromaticity of a composite display surface combining the display surface and the background, and control the chromaticity of the display surface such that a chromaticity difference between the chromaticity of the background and the chromaticity of the composite display surface is equal to or more than a certain value.
