Rindou color

The color is a slightly pale purple, named after the dragonfly flower. The flowering period of the dragonflower is from September to November. Its roots are used in Chinese herbal medicine, and the Chinese character for "dragon's gall" was given to it because of its intense bitterness, like that of a dragon's gall. Along with the bellflower, it is one of the most representative flowers of autumn in Japan.
