PS says this dress is blue and black.

These two days the most people talk about is actually a skirt, and still an ugly exposed skirt! TUMBLR user swiked posted a photo, causing the internet a commotion, because everyone is talking about the color of this dress! The answer is divided into two major factions, the first is to see blue and black, and the second to see White and gold.

On the color of the dress, the vote on the BuzzFeed reached 1 million people, and 73% of the people saw white and gold.

But if you use Photoshop to analyze it, it's obviously black and blue, and even though it's barely orange, it's obviously not white.

It is pointed out that this dress should be the following one (although a shoulder is missing), so this skirt is originally blue and black!!!

A certain treasure chromatic aberration of both visual sense!

Why is this so? Small partners in different fields have contributed to their ideas.

White balance

This phenomenon is actually the human eye strong automatic white balance function caused by the tangle. For example, when the white balance is pushed to the most warm, it is white and gold.

The original photo (medium) and after a different white balance adjusted to render the white-gold (left) or blue-black (right) two forms

Negative post like

Perhaps, it is similar to the following picture of the negative image (Negative afterimage) effect, that is, the parties see other strong colors, and then back to look at the skirt, and then create an illusion. As a result, many people point out that when they look at their skirts more than two times, they "turn back" to blue and black.

Psychology/Biology

Many people have analyzed that this is a psychological/biological factor, that is, we see the image and color, is actually affected by the environment, such as the next picture is very famous, A and B are in fact the same color, but it looks a deep and shallow, in fact, is affected by the background information.

In the figure below, the seemingly lighter color block B is surrounded by dark patches, so that even though its actual color is dark, the brain still thinks it's brighter. Instead, the color block A is surrounded by a lighter color, so the brain finds it darker.

Science and technology issues

But if it's not a psychological factor, could it be a technical problem? For example, the same picture, appearing on me and your computer, has very different results, like some Web sites that don't support Adobe RGB, and then they turn into weird colors. But if that's the case, take a picture on your device with your cell phone to show that there are other devices that show different colors.

Medical

The foreign doctor did the experiment and concluded that the primary color of the skirt was bluish black. And those who can see the blue-black, the retina cone is more sharp, perceptive ability, eyes can reduce clutter interference. See platinum people are in the light of the case of color is prone to deviation, retinal cells see white, light is not sensitive, will see additional color mixing, so see gold.
