Some mediums can see auras. Not all of them though. You can sometimes teach yourself how to see them but you will need a lot of patience and continued practice.
The auras are made up of all the rainbow colours. The colours are often varying shades and pulsate. The aura can be quite well spread out from the persons material body.
The idea of reading them is mostly reading the colours. Again, a lot of work with the spirit guide will be priceless. The partnership is invaluable. Apart from the colour itself, the density of the colour is also important.
Some mediums and healers can actually diagnose illness by examining the aura. But, never have this instead of a doctors examination. The two would be good though.
The chakras are part of the etheric body, at certain points corresponding to the material body. The important thing here is the colour of them. If you use this blogs search facility at the right side of this page, you can learn more about the chakras.
If you focus on the colour of certain chakras, you will be able to develop certain psychic senses. Again, dedication is required. Not to mention determination and persistence.
More on colour tomorrow!
