From the color aesthetics of the famous Italian painter "Morandi"
His philosophy of life is: "The more simple and mundane objects are, the more they can be released from redundant interpretations."
Morandi added a certain proportion of off-white to all colors, commonly known as high-grade gray.
When the overall brightness and saturation of the picture drops, a little bit of "gray" can bring out the overall texture, which is what we usually call elegance and high-end.
