Current visualization techniques for mapping polarization data to a color coordinates defined by the Hue,
Saturation, Value (HSV) color representation are analyzed in the context of perceptual uniformity. Since HSV is
not designed to be perceptually uniform, the extent of non-uniformity should be evaluated by using robust color
difference formulae and by comparison to the state-of-the-art uniform color space CAM02-UCS. For mapping just
angle of polarization with HSV hue, the results show clear non-uniformity and implications for how this can
misrepresent the data. UCS can be used to create alternative mapping techniques that are perceptually uniform.
Implementing variation in lightness may increase shape discrimination within the scene. Future work will be
dedicated to measuring performance of both current and proposed methods using psychophysical analysis.
