I rarely fall for these sorts of optical illusions because I’ve spent years taking and editing photographs (some of those as a full-time job).
Didn’t look white and gold or blue and black to me.
Immediately looked brownish gold and blue, and two seconds in Photoshop sampling the colors confirmed this.
Hard to believe that anyone can see it as anything else, but those sorts of color-based optical illusions I’m now almost completely immune to. (Others I fall for just as much as anyone else.)
(Also note: There is no “real color” that the dress is as far as the camera is concerned. It can only be known objectively the reported color values on the screen, which are influenced by camera white balance, light levels, contrast ratio, compression, filters, sensor quality and optimizations and a host of other factors.)
