The "Eight Prangs" The form of a Thai Prang (tower) derives from the Khmer prasat, but whereas a prasat is "a residence of a king or a god," a prang has the same function as a chedi. The "Eight Prangs" are of different colours. Each one is dedicated to a certain Buddhist concept, as follows:

White : The Buddha Sakayamuni

Purplish Blue : The Teaching of the Buddha

Pink : The Community of Buddhist Monks

Green : The Buddhist Female Monks

Purple : One who has attained nirvana but who is not able to preach the knowledge to men

(P. pacceka-buddha)

Dark Blue : The Universal Monarchs

Red : The Buddha in his Former Lives

Yellow : The Buddha Maitreya, the Future Buddha
