As stylists like to
say, gray is the color of balance, it is neither dark nor bright. If a person has a lot of gray clothing
it usually means they want to remain invisible.
Gray and its shades are a symbol of tranquility, dimensionality, and maturity. Many middle-aged men wear gray suits, while women of older ages wear gray dresses.
Since this is a neutral color, it is extremely difficult to characterize the person who prefers it. They could be a gray mouse ready to silently obey the rules, as well as a judicious, low-emotional, and categorical person.
But in most cases, a person who favors gray is someone who does not like to attract attention and tries to maintain neutral.
