The pursuit of simplicity is the decoration effect that Japanese soft clothes want to achieve. Therefore, when choosing colors, Japanese soft clothes also choose those refreshing and simple colors, rather than too bright colors. "White, black, cyan and red" are the four main colors that run through Japanese soft clothes. White and red in Japanese soft clothes mostly refer to the color of logs. Japanese decoration uses a lot of wood, such as tatami and bamboo. Using these two colors can help people build a simple and relaxed spiritual home. Solemn black is associated with Japanese Zen culture, and it is also a favorite color in Japanese soft clothes. Cyan is mainly influenced by the green mountains and green waters of the Tang Dynasty in China, and now it has become a favorite color in Japanese-style soft clothes.
