Powerful Deep Blue Aura? Insight?

One of my friends has this beautiful blue aura. I never really noticed until recently, but the color is so clear in my mind now that whenever I see him or think about him I immediately think of the color blue. It's not a bright blue, more of a royal blue or maybe even darker. It's not a dark blue, but it's such a clear blue it almost seems that it's dark. At some times I feel it could be tinged with violet as well. I didn't used to be, but now whenever I'm with him I get a little nervous because his energy is so present. It's intense and honestly entrancing to be around him. I don't have much practice with channeling my gift, so I don't know exactly what this could mean. From what I feel I think he's special somehow. Almost an ethereal person. I have this longing to hang out with him all the time because it's fascinating, it feels like I'm deep under the sea when we're together. I don't have feelings for him other than sincere amazement, but I've refrained from telling my friends about how I feel because I know they won't understand the difference. I've also recently gotten into astrology, he is a Scorpio sun, Leo moon, and ascendant in Sagittarius. I'm a Leo sun, Leo moon, and ascendant in Scorpio. I don't know if that's relevant, but hey it's giving me extra characters. My post was a little short because I don't have much else to say about my experience. Could someone please help me with this? I'd really like to have insight from others with this gift (talking about auras with my friends weirds them out a little). Thanks so much!
