Now, the neurons fire the way they do because of electrical signals that are sent to them by the eyes, but electrical signals aren't colors either—they’re just, roughly put, moving electrons. And your eyes send the signals they do because of the way wavelengths of light interact with their rods and cones. But, again, it's not like different wavelengths of light are actually different colors. The study asked 1,401 people (313 of whom hadn’t seen the dress image before) about the color of the garment. Out of the people surveyed, 57 percent of the people described it as blue/black, with 30 percent describing it as white/gold.
Our eye’s photoreceptors receive light rays from the sun and convert this into nerve signals. The nerve signals so received are processed, in turn, by the nerve cells in our inner retina, which is then passed over to our brain to be translated as messages. In the photo posted on Tumblr, the dress fills up most of the image, providing very little information about how the object is being lit. "The wide range of interpretations about how it's being illuminated leads to a wide range of interpretations about its intrinsic color," Williams said.
How is the black and blue dress white and gold?
The Royal Regiment of Scotland wears a short jacket called a "doublet", in Archer Green. Prior to amalgamation, Highland regiments wore the doublet with the kilt and sporran while Lowland regiments wore trews, both in the individual regiment's tartan. People who saw the dress as a white-gold color probably assumed it was lit by daylight, so their brains ignored shorter, bluer wavelengths.
Older people and women were more likely to report seeing “The Dress” as white and gold, while younger people were more likely to say that it was black and blue. A study carried out by Schlaffke et al. reported that individuals who saw the dress as white and gold showed increased activity in the frontal and parietal regions of the brain. These areas are thought to be critical in high cognition activities such as top-down modulation in visual perception. On 3 March, the Johnstons, Bleasdale, and MacNeill appeared as guests on The Ellen DeGeneres Show in the United States. Lacking L or M cones has minimal impact on perceived dress colors while a lack of S cones yields a very different perception suggesting a primary role of the S cone input in perception of the Dress. "If you see the dress in shadow against a bright background, you will see it as gold and white. If you see the light as coming round behind you, you will see the dress as blue and black."

In the case of The Dress, researchers suggest that the differences in opinion on the colours depend on whether the viewer believes the photo was taken inside or outside. There is no one definitive answer to the question of what the “real” color of the illusion dress is. It depends on the specific dress, and on the lighting and angle at which it is viewed.
The dress may have appeared blue with the colour cast, but after white balance it can appear white. For the situations where different people are looking at the same screen or printed photograph, my guess is that the variability comes from the color/brightness/etc sensitivity of their eyes. For example, in my own eyes, one of them sees the wall in a brighter shade of white than the other eye. Perhaps those who aren't as sensitive to blue might see the blue/white part of the dress as a shade of white, and call it white. I don't know why it doesn't trick me, I usually fall for optical illusions.
Is This Dress White And Gold Or Blue And Black? A Scientific Look.
It consists of a stone coloured bush-style four-button jacket worn with or without a shirt and tie underneath and stone coloured trousers. It is worn by all ranks for parades (as with No. 2 Dress), unless No. 3 dress is worn, and by ORs for all other occasions. No. 1 dress originated in the "undress" uniforms ('blue Patrols') worn for semi-formal or ordinary duty occasions in the late 19th century.
Officers and Warrant Officers Class One of some regiments and corps wear a leather Sam Browne belt (that of 1st The Queen's Dragoon Guards is of pig skin which is not to be highly polished) or a cross belt. Infantry Warrant Officers Class Two and SNCOs wear a scarlet or crimson sash over the right shoulder to the hip. Soldiers wear a white or black plastic waist belt with a plate buckle displaying the regimental badge in ceremonial uniform – a plain khaki belt in non-ceremonial. A different type of frock coat is worn by certain officers of the Household Division, Honourable Artillery Company and King's Troop of the Royal Horse Artillery.
Blue and black, or white and gold? The science behind The Dress debate
The average VEP waveform in response to 70 pattern onsets was recorded twice from each subject and amplitude in microvolts (?V) vs. latency (msec.) were exported as digital values to compare VEPs across BB and WG groups. Those who originally saw The Dress as blue and black should not be too smug, though. Some may argue that colour itself is just a construct imposed by the brain to make sense of the world.
Our brain is responsible for the colors that we eventually see, as it takes all of these signals received by the different receptors and blends them together to form the final image we perceive. In the case of the blue and black dress, the brain interprets the colors differently depending on whether the dress is seen in shadow or in direct light. The blue and black dress illusion highlights the importance of lighting in color perception. It also shows how the human brain is constantly interpreting the world around us, and how our perception of reality is often subjective. The blue and black dress illusion was a phenomenon that occurred in 2015, when people were divided on whether a dress was blue and black or white and gold. The illusion caused a lot of debate and discussion, with people taking sides on what they saw.
