Historically the dragon dance may be performed in a variety of ways with different types and colours of dragon. Green is sometimes selected as a main colour of the dragon, which symbolizes a great harvest. Other colours include: yellow, symbolizing the solemn empire; gold or silver, symbolizing prosperity; red, representing excitement. The dragon's scales and tail are mostly beautiful silvery and glittery to create a joyous atmosphere. As the dragon dance is not performed every day, the cloth of the dragon is removed and touched up with ultra-paint before each performance.
