Image shows two drawings of a dress that was featured in a viral internet post in 2015. People had difficulty agreeing on whether the dress was black and blue or white and gold. The drawing of the dress on the left has half of the dress against a black background and the other half against a background that corresponds to the black-or-gold color on the dress; the drawing of the dress on the right has half of the dress against a white background and the other half against a background that corresponds to the blue-or-white color on the dress. Text on the left reads "Black dress, yellow light." Text on the right reads "White dress, blue shadow." This illustrates how the colors of the dress can be perceived as either black and blue or white and gold depending on the viewer's intuitive perceptual context assumptions, showing that a sensation or sense-data that is "black" in one Gestalt can be the same as a sensation that is "gold" in another Gestalt.

Image of several hygiene and cosmetic products on a bathroom countertop. Only the front-most product’s label can be seen and read. Cropping is tight, so that the overall impression is that of a picture of one product with nondescript other bathroom products behind it. Product is 30 spf sunscreen, but “e.l.f. skin” are the most prominent words on the label. Although e.l.f. Is a well-known brand name, the periods between letters are small, making it easy to misread as “elf skin”.
