Hello everyone who‘s part of Satan‘s house!

I am learning astrology currently abd I stumbled across one of Aldrick‘s Videos on Youtube. He explains how you can figure out what your aura-colour is.
Here is the Video:https://m.youtube.com/watch?v=uu_pVwaocBU

Okay now leading to my issue, I have no Planets in their exalted or home signs, except of Uranus.
Uranus is also a co-ruler of my chart. Does it mean that my Aura has the colour which relates to Uranus? Or is there another way to figure it out with the natal chart?

Thanks for your advise in advance
