Why are winter clothes mostly dark? Is there any other reason besides not getting dirty easily? It is best to start with season+color psychology.

From a seasonal point of view, it should be based on the principle of reflection. It is cold in winter, so an important parameter of clothing design is to keep warm. The depth of color directly affects the light absorption of clothes. Light color has good reflection effect, which means most of the light is reflected away, which means less heat is absorbed. The poor reflection effect of dark color means that it absorbs more light, which can keep clothes warmer to some extent.

From the perspective of color psychology, I don't really think about it now. If we talk about colors, I think red, yellow and orange are warm colors, while blue, green and gray are cool colors. However, with the growing sense of fashion, there are all kinds of colors, so I don't think much about cold and warm colors, but no matter what colors, most of them are dark, which can basically absorb light and heat better.
