For anyone interested these are the centres and their position. The colours are not the colour of the centre, but the colour that enhances the centre. These centres develop at different ages. Crown 5, Third Eye 6, Throat 7, Heart 8, Solar Plexus 9, Navel 10, Genital 11, Base 12, and the Aura at 13. Also for anyone interested...the reason for the Bhamitzva at the age of 13 is because that is when the final centre is developed and although this knowledge has probably long since been forgotten, this was considered when the child became "whole". Hence the celebration. Just throwing it out there folks.
