The Mayan and Chinese cultures (China, Japan, Vietnam, etc.) did not distinguish between blue and green in ancient times, and both wrote "qing" (青).
The ancient Chinese character for blue, "qing", could describe both green and black (e.g., xuanqing), as is the case today in Foochow or Minnan.
Vietnamese also does not have a specific word for green, but the word "xanh" (儒字: qing) can mean both green and blue.
Modern Japanese has words for green (綠/みどり，midori) and blue (青/あお，ao). The word "midori" originated in the Heian period, when it referred to one of the colors of "あお". After World War II, textbooks used the two words to refer to green and blue, respectively. In modern Japan, the word "midori" is mainly used to describe green things, while "あお" is used to describe green traffic signals and plants.
Green means harmless and healthy, such as green vegetables.
