Tibetan prayer flags are bright and eye catching. Each colour represents an element. Blue for the sky, white for air, red for fire, green symbolizes water, and yellow symbolizes earth. All five colours together represent harmony and balance. According to Buddhist legend, the first prayer flags were used by Gautama Buddha but you don't have to be a Buddhist to hang them. But there is a right way to hang them, while putting your flags up wherever you would like, it's important to keep good, selfless motivations in mind, in keeping with the flags' ultimate purpose, which is spreading positivity and balance.
