Aura is your energy field, it changes from time to time as the energy surrounds you and radiates from your body is influenced and powered by your inner energy or what is known as chakras.
You have a basic colour which matches your own personality and soul growth and your overall aura can remain the same unless you experience a subtle or dramatic change or shift in your energy field.
Body scanning is also available . I see the physical body as it is like in3D. I can see the whole body, skeletal system and the organs as well. I can see if there is any discomfort or issue that needs attention.
Please note this does not substitute a medical practitioner.
