All colours have a uniquely coloured aura of their own that are of a completely different colour.
These auras, given off by colours, are denser and far easier to see than any other aura. Using this as a basis, I have designed a simple, graduated training method that has most people seeing an aura the first time they try it. The auric colours you will see building up from coloured objects are similar in appearance to the after images generated by staring at a brightly coloured shape and then quickly looking at a neutral coloured wall. The similarity in the colours, rather than contradicting the validity of the auric colours of colour, confirms them. You can, in the early stages of learning to see auras, cause an after image that is still seen when you look away.
