1. A method comprising:
at an electronic device including one or more processors, a non-transitory memory, and a see-through display:
determining a plurality of light superposition characteristic values associated with ambient light from a physical environment, wherein the plurality of light superposition characteristic values quantifies the ambient light;
modifying image data in order to generate modified image data, based on a function of the plurality of light superposition characteristic values and a reference perceptual gamut;
transforming the modified image data into display data based on a function of a portion of the plurality of light superposition characteristic values and a reference physical gamut that is associated with the see-through display, wherein the reference physical gamut characterizes the see-through display as a nominal amount of ambient light from the physical environment enters the see-through display; and
displaying the display data on the see-through display.
