Use the texture of the fabric to create a combination of silver and steel. Especially in the surface with fog color to illustrate the true softness, there is a difference with the actual touch. Gray is a series of colors between black and white. Deeper than white, lighter than black, darker than silver, colder than red, interspersed between black and white, even more darkly beautiful. It is not purer than black and white, but it is not similar to black and white. It is like chaos and always changing and changing, but it is the most like a Human color. Just like as people.
