There are (apparently) a 100 of those blue petals - one for each of the Kauravas, and 5 of the green ones in the centre - one for each of the Pandavas. The green bulb in the centre symbolises the Pandava queen Draupadi, and the three filaments are for the holy trinity of Brahma-Vishnu-Shiv. AND the white radial in the centre is the Sudarshan chakra of Lord Krishna.
