Perceptually, one of the strongest memory colors is skin tone. Get it wrong and it’s hard to miss. Image adjustments are commonly applied for preference-based image enhancement, and they are applied across a variety of color spaces, so it’s important to understand the effects these procedures have on skin tone appearance. In this paper, we present results of a psychovisual experiment that explores the perception of skin tone under changes in hue, chroma, and intensity. Through coupling the effects each axis has on perception of different skin tones, viewer expectations of color appearance can be evaluated. The experimental results convey a low tolerance for changes in hue when altering intensity and chroma and a high tolerance for changes in intensity across all adjustments. When altering intensity, the results present changes in chroma that follow the shape of the ITP gamut hull. There was some variability between skin tones. This speaks to how individual skin tone classification may be helpful to preserve colorimetric appearance following adjustment.

This research looks to understand the perception of skin tone in images from a colorimetric level. By focusing on the three components of color (hue, intensity, and saturation), we gain perspective on how each influences appearance differently when evaluating memory colors
