My character Trynor, a spirit guide in "Despite the Angels", is tweeting these days, and has just made a comment about soul colours. This information comes from the work and observations of Dr Michael Newton, who regressed maybe 8,000 people to the "Life between Lives".
He reports that very young souls are bright white, and there is then a progression of colours through yellow to green, to blue and lastly to purple as souls mature and gain wisdom.
There is no virtue in being an 'old soul' compared with a young one, any more than it is virtuous to be in the final year of secondary school compared with being in kindergarten. It is just a matter of time.
Read more in 'Journey of Souls' and 'Destiny of Souls' by Michael Newton.
