After the blending of purity, gray no longer exists independently as a chromophore, but achieves its versatile quality. Mixed with a little beige, it will give people a softer touch, alleviate the depression of grey space; the combination of "advanced grey + golden" is fashionable, light and luxurious, without losing taste. Grey, darker than white, lighter than black. Darker than silver, colder than red. Gray, implicit, soft, neutral and accommodating. Some people have given such a formula - "plain"+ "simple"+ "advanced gray"= temperament. Whether it is a new middle class with a low-key and introverted attitude, or a small refreshment after the 1980s and 1990s, there is no one who is not "advanced" with gray. SO, in this sense, gray, advanced, is also the mainstream!
