What is the evolutionary advantage of a panda's black and white?

Scientists do not always have the answers, and scientists often disagree. Take, for example, the red black and white ringed coloration of the coral snakes and their "mimics." Many scientists believe that these colors are aposematic, or warning coloration. However, some people, including yours truly, disagree, and point to the fact that the red, black and white colors actually blend in quite well with the woodland and forest habitats of these snakes, because the red matches the fallen leaves and tree bark in color. The black color would blend in with the shadows of a woodland, and the white or yellow color would be a good match with the sunlight filtering through the branches. BTW, I have found many photos of zebras becoming nearly invisible when they stand in brushy areas or wooded areas, not just grassy areas. The zebra's dark stripes blend in well with the branches of trees and shrubs as well as dark areas not lit by sunlight, and the white color also blends in well with the sunlight shining through the branches. Interestingly, many scientists do not even believe that the zebra's color pattern is good camouflage.

Pandas live in high altitude, forested areas, where snow is common in winter. The white coloration would match the snow cover, and the black areas look like tree trunks emerging from the ground. That is my opinion, but others may or may not agree. As to why they have dark ears and dark eye patches, I have no definitive answer. Perhaps the dark eye patches disguise the eyes, rather than make them larger, because if you look at eye spots found on the tail feathers of the peacock, on the wings of a butterfly or on the body of a fish, they tend to have a dark area in the middle (resembling the pupil) and a light area (resembling the iris) surrounding the dark center. See the following image for example,

When we look at the eye patch of the giant panda, they don't resemble an eyespot at all. So, it is more likely just a camouflage for the eye, rather than a warning display that makes the giant panda appear bigger than it already is. Similarly the black ears may disguise their presence, because a white head with white ears may stand out more than a white head with dark ears. Since eyes and ears are commonly found on animals, but similarly shaped objects are seldom found in nature, the giant panda therefore may have evolved ways to disguise these features that immediately attracts the attention of other animals.
