In the Christian tradition, the Rainbow is a symbolic bridge between Heaven and Earth, the Covenant between God and humanity after the Flood. The seven colours, similarly, recall the seven fold unity of God and His Creation.
It is also a symbol of hope because the rainbow appear after the heavy rain.
The Rainbow is often connected with creation deities in many of the Australian Dreamtime stories. Many Aboriginal Australians associated the rainbow with the similarly coloured serpents that lived in deep pools of water. Because of the snake's colour and association with water, the deity of the Rainbow Serpent was seen as either a giver of life and water, or a cause of dehydration and drought.
