From: The most reasonable explanation of “the dress”: Implicit assumptions about illumination Journal of Vision. 2017;17(2):1. doi:10.1167/17.2.1 Figure Legend: Photo of the dress. (a) Original photo of the dress (Swiked, 2015). Many observers see the dress in this photo as striped gold and white, and many others see it as black and blue. Disambiguating the illumination as in Figure 2 and Figure 10 influences the perception of dress colors. (b) Color distributions in the photo. Light red dots show the colors of the dress and light green dots the colors in the rest of the photo (i.e., the background). The saturated red and green disks show the average color of the dress and the background, respectively. The red line illustrates the main variation of the color on the dress through the first principal component. The colored curve shows the Planckian locus to illustrate the variation of daylight. Note that the colors of the dress vary approximately parallel to the daylight locus (Gegenfurtner et al., 2015), and the average color of the background is aligned with the variation of colors in the dress.
