This statement was not completely correct. Although people usually thought that crows were black, in fact, if one observed carefully, under a certain angle of sunlight, the seemingly black feathers of crows would appear blue-purple or blue-green with a metallic luster, not pure black.

The water of the Black Sea was black on the whole, which was why it was named the Black Sea. In the Black Sea, where Russia was located, the water was also black. This was mainly due to the unique geographical and environmental factors of the Black Sea. On the one hand, the average depth of the Black Sea was deeper, which made the color of the sea look darker. On the other hand, there was more silt at the bottom of the Black Sea, and many rivers around it flowed into the Black Sea. The passage connecting the Black Sea to the outside world was long and narrow, resulting in more water and less water. The silt carried by the rivers piled up at the bottom, making the Black Sea look darker from the outside. In addition, the seawater below 200 meters of the Black Sea was almost not exchanged with the outside world. The lower seawater had low oxygen content, and a large amount of sludge and debris accumulated here. Sulfur bacteria decomposed a large amount of organic matter in the seawater to form hydrogen sulphide and mixed it with the seabed sludge, which also contributed to the black sea. However, the seawater of the Black Sea was clear and transparent.

This statement was not completely correct. Although crows usually appeared black to humans, crows were not purely black. Under a specific angle of sunlight, the black feathers of common small-beaked crows, large-beaked crows, bald crows, ravens, and other species would appear blue-purple or blue-green with a metallic luster. Moreover, due to the special structure of the human eye, it was impossible to see the true color of the crow's feathers. In the eyes of birds, the crow's feathers were colorful, just like the gorgeous appearance of a peacock. "The Crow's Testimony" is equally exciting. Everyone is welcome to read it!
