Many believe energy has no color and/or its color is meaningless. While others believe energy has color and your energy color gives you certain strengths in the aspect that align with your color. I will present both views.
~Energy Has No Color~
Energy has no color.
~Energy Has Color~
Energy does has color, that's why it manifests in colored auras around the body.
If it had no color then you couldn't see it, only detect it.
~Has No Color~
Well even if it does the colors have no meaning.
Well it may have meaning. Scientifically certain color energies are more power. Here's a list from most powerful to least: Red, Orange, Yellow, Green, Blue, Indigo, Purple.
Certain energies may even be more powerful to certain practices.
That's my theory. I hope you thoroughly read this. Please give me intelligent feedback. And don't be a d**k.
