When clues about ambient light are lost, one may perceive the same color in a different way.
Related article on Tumblr, a photo of a dress sparked an internet discussion: What color is it?
Some people see a white and golden dress in the dark shadows.
Some people see a blue and black dress washed out in bright light.
Some people see an explanation and switch to another one.
Let\'s take a look at this photo where the striped dress takes up most of the frame.
If we take two clothes in Photoshop and average color, we get a flat color pattern: the basic pattern of two clothes will we explain these colors?
Our eyes are able to specify a fixed color for the object under different lighting conditions.
This ability is called color persistence.
But this picture does not give a lot of clues about the ambient light in the room.
Is the background bright and the clothes have shadows?
Or is the whole room bright and all the colors washed out?
Different people may get different visual cues from the image, which may change the way they interpret and name the color.
Is there a shadow on this dress?
Is the dress in the photo in bright light?
If you think there is a shadow in this dress, your brain may remove the blue dress and think the dress is white and golden.
If the photo shows more rooms, or if the skin color is visible, then there may be more clues to the surrounding light.
If you think the dress has been washed off by a bright light, your brain may think the dress is dark blue and black.
What is the answer?
Other photos show that the dress is actually blue and black.
In the second photo, white wedding dresses, dark curtains, visible skin tones and body shadows help us to accurately judge the ambient light in the room.
