A double rainbow is considered a symbol of transformation and is a sign of good fortune in eastern cultures. The first arc represents the material world, and the second arc signifies the spiritual realm. According to Chinese mythology, red represents the feet, and violet symbolizes the head. Therefore, a single rainbow signifies a human descending from heaven to earth. A double rainbow, due to its reversal of colours, represents the movement from earth to heaven and is considered to be a sign of future success.

A friend of mine sent a wonderful pic of double rainbow in London, it tickled muse and resulted in this lovely poem poster “Double rainbow”.
