What kind of blessing does the color yellow represent in Japan? Is it related to health?

Japanese people like red, white, blue, orange, yellow and other colors, and taboo colors such as black and white, green and dark gray. In Japan, it has been a custom since ancient times to use yellow clothes for newborn babies and yellow cotton for quilts for patients. This is because yellow is considered the color of sunlight and can keep warm. The meaning of safety colors stipulated in the Japanese Industrial Standards (JIS): red means fire extinguishing and stopping; orange means danger; yellow means attention; green means rescue and traffic; blue means caution; white means the road is under construction.
