We all associate yellow with the color of the sun – so it follows that a yellow aura often denotes a person with a sunny personality! Somebody who naturally draws people to them, people like to be around them, basking in their light!
The out of balance yellow may denote someone who wants to withdraw, not be 
around people, not be in the mood for making other people laugh right now.
A bright yellow is a bit like a “breath of fresh air” - not just the personality but it denotes a clarity of thought and decision. It is like clearing the mind of clutter, allowing pure intent and focus, room to breathe.
You guessed it, the darker or smudgy tones may well denote a lack of focus and clarity!
If you want to improve your concentration, have something close by that is yellow or visualize a yellow light, clearing your mind, leaving you sharp and focused.
It has the fresh, sharp cleaning ability of lemons and the zest to make it work!
Yellow sits with the Solar Plexus Chakra, linking with our will, our core personality.
It also is directly linked with the core of our physical body; our gut – our digestive system – our immune system.
