The dress illusion is a viral phenomenon that occurred in 2015, where a photograph of a dress caused debate and disagreement over the actual colors of the garment, which appeared to some people as black and blue and to others as white and gold.
This phenomenon is believed to have been caused by the way different people perceive colors, as well as differences in lighting conditions and individual differences in color vision.

How does the Dress Illusion work?
The dress illusion works by tricking the brain into perceiving colors differently.
This occurs because the brain uses various cues, such as lighting and context, to interpret the colors in an image.
In the case of the dress illusion, the photograph was taken under ambiguous lighting conditions and had no clear context, which led to different people perceiving the colors in different ways.
Some saw the dress as being white and gold, while others saw it as black and blue.
This phenomenon is believed to be related to the way that the brain processes color information from the cones in the eyes.
Different people have different levels of sensitivity to different colors and may interpret the same image differently based on their individual visual system and the way that they process color information.
Additionally, the way that the brain processes colors can be influenced by prior experiences, cultural background, and other individual factors.
Versions of the Dress Illusion
The following are some versions of the Dress Illusion:
Illusions like Dress Illusion
The dress illusion is a type of color perception illusion, specifically a chromatic illusion.
A chromatic illusion is a type of illusion in which the perception of color is altered, despite there being no change in the physical properties of the stimuli being viewed.
In the case of the dress illusion, the image was perceived as having different colors by different people, leading to confusion and debate about the actual colors of the dress.
The following are some illusions that are related to the Dress Illusion
Chromostereopsis is an optical illusion that involves the perception of depth and three-dimensionality based on color information. It is caused by the differential refraction of light of different wavelengths, known as chromatic aberration, as it passes through a lens.
In chromostereopsis, objects that are red appear to be closer than objects that are blue. This illusion is due to the fact that red light has a longer wavelength and is bent less than blue light when it passes through a lens. As a result, red objects appear to be closer to the observer than blue objects, even when they are actually at the same distance.
An autostereogram is a type of image that appears to be a flat 2D image when viewed normally, but when viewed with a special technique, it appears to be a 3D image with depth and perspective.
Autostereograms are created by repeating a pattern of repeating elements, such as random dots, in such a way that the repeating elements at different depths in the image align with each other when viewed with the special technique. This creates the illusion of a 3D image.
The image below appears as a 2 dimensional flat image, but when viewed using one of these techniques mentioned below, a 3 dimensional shape appears.
The Bezold Effect is a phenomenon in color theory where a change in one color can cause the perception of the surrounding colors to change as well.
This effect is caused by the way the human visual system processes color, and it is often used in art and design to create the illusion of depth or movement.
Binocular rivalry is a phenomenon that occurs when slightly different images are presented to each eye simultaneously.
The brain is unable to fuse the two images into a single, coherent image, and instead alternates between perceiving one image and then the other.
This can cause the perceived image to flicker or change back and forth between the two images.
Troxler’s fading, is a phenomenon in which a stationary visual stimulus eventually disappears from perception, even though it is still present in the visual field.
This occurs because the human visual system adapts to constant stimuli and eventually stops responding to them.
The Phi phenomenon is the illusion of movement created by the rapid succession of static images or light sources.
It is the perceptual phenomenon that explains how the human brain perceives motion when presented with a sequence of still images or light sources that are displayed in rapid succession.
The Rotating Snakes is a peripheral drift illusion that consists of a grid of shapes, with some of them appearing to be rotating or undulating. The illusion is created by the interaction of the shapes with the neural processing of the visual system.
The Scintillating Grid Illusion, in which a grid of black and white squares appears to pulsate or “breathe” when viewed from the periphery of the image.
The Hermann Grid Illusion, in which the intersections of a white grid on a black background appear to be gray, even though they are actually the same color as the background.
Silencing is a visual phenomenon where objects that change in luminance, hue, size, or shape appear to stop changing when they move. They “freeze” in place.
This illusion can be created through various means, such as flashing lights, or rapidly moving a stimulus back and forth.
The Café Wall Illusion is a visual illusion that is created by a grid of alternating light and dark horizontal and vertical lines. The lines appear to be bent or tilted, even though they are actually straight.
These illusions are usually caused by the way our eyes process visual information and the way the brain interprets it. They can also be caused by the interaction of different visual elements, such as lines and angles, in the image. They are often used in research on visual perception and the neural basis of perception.
Discovery of The Dress Illusion
The dress illusion was initially discovered by Caitlin McNeill, a singer and musician from Scotland, who posted a photograph of the dress on her Tumblr account in early 2015.
McNeill had noticed that people in her social circle were perceiving the colors of the dress differently and wanted to see if others would have the same experience.
The photograph quickly went viral and sparked widespread debate and discussion about the actual colors of the dress, leading to the phenomenon being referred to as “The Dress Illusion.”
