yes auric is interpretation is very much open to the person.
Colours can mean things.
1. Emotions, what the person is feeling
2. Experiences, the past they have had
3. personality, studies show that happier people tend to have more lively auras
Auras can also be interpritated by there layers. Auras, as far as I am concerned, have 7 layers.
These layers can vary in colour which can be interesting enough.
I'd recommend you try not to touch the auras to much or interfear with them as there are many planets that doing that would be like fondling someone. with out permission.
When looking at auras, look but do not touch is my legacy.
