The meaning of the colors in Chinese culture:

The I Ching, or Book of Changes, regards black as Heaven’s color. The saying "heaven and earth of mysterious black" was rooted in the observation that the northern sky was black for a long time. They believed Tian Di, or Heavenly Emperor, resided in the North Star. The Taiji symbol also uses black and white to represent the unity of Yin and Yang. Ancient Chinese regarded black as the king of colors and honored black longer than any other color. Lao Zi said that "five colors make people blind," so the Dao School chose black as the color of the Dao.
White represented gold and symbolized brightness, purity, and fulfillment. White also is the color of mourning. Ancient Chinese people wore white clothes and hats only when they mourned for the dead. That tradition is still practiced today.
The Chinese people, both ancient and modern, cherish the color red. Red is everywhere during Chinese New Year and other holidays and family gatherings for it symbolizes good fortune and joy. Unfortunately, since the Communist takeover of China, red has been used by the Chinese Communist Party to represent danger, blood, violence and radical actions.
Blue-green indicates spring when everything overflows with vigor and vitality.
Yellow symbolizes the earth. The old saying, "Yellow generates Yin and Yang," meant that yellow is the center of everything. Yellow was the symbolic color of the five legendary emperors of ancient China. Placed above brown, yellow also signifies neutrality and is considered the most beautiful color. Yellow also represents freedom from worldly cares and is thus esteemed in Buddhism. Monks' garments are yellow as well as Buddhist temples.
Color embodies an even richer culture in Chinese folk traditions. Yellow is the color for emperors. Yellow often decorates royal palaces, altars and temples. Yellow also represents being free from worldly cares. Therefore it is also a color respected in Buddhism.
