Different Aura Around Hands?

I've noticed that my aura has changed from blue to green in the past year, but the aura around my hands is still purely blue and the rest of my aura only has hints of blue. That brings me to the question. Why is the aura specifically around my hands different from the rest? I've noticed this on only a few other people as well. Sometimes when I look at it, my aura has changed back to green around my hands as well as around the rest of my body, as if it alternates between the two colors. The only thing I could find about this was that blue around the hands means you are a writer/ artist. It would make sense because those are my two favorite things to do and I'm apparently "good" at doing so, but I don't know if it is true. I also read that green around the hands means you are a healer, which would also make sense because my hands do heat up and tingle at random, I tend to shock people a lot (as if there were static electricity) when this happens, usually people come to me when they feel down, and I have been able to create balls of energy before. Usually my hands are green after experimenting with energy and blue after drawing/writing, but sometimes this is not so. Does it really have to do with these things? Is this normal? Why does my aura do this (specifically why the aura around my hands changes colors and why it is a different color)? What does this mean? I would just like to know your opinion on this. Oh, and on a side note, does being around people with a different aura color influence changes in your own? I apologize since I don't know much on this. Thank you in advance!
