Some zoologists have pointed out that most mammals, except humans and apes, are color blind and have no ability to distinguish colors. Reptiles are color blind, while birds have the ability to distinguish colors. Elephants can only distinguish several colors (achromatic color color), and their eyesight is poor, so they are color blind.

If you have read the related reports such as "Elephant Painting", you may wish to pay attention to the decryption of "The Truth Behind Elephant Painting". Elephant painting is not because it can distinguish colors like human beings, or because it has creative thinking, but because it is a mechanical reaction after compulsory training, which is purely a hype of tourism and zoos. It is impossible to judge the colors that elephants can see.
