"I've never thought about it much before, but now that you mention it, I suppose you could say I see them in colour," Tsaba explained. "It's rather difficult to see much; or more accurately, there's too much going on that I don't understand to really pick out anything useful, like trying to see fish under a chaotic ocean in the sun. Auras move, at least living ones do, and the information isn't so much in the image but in the pattern. For me, anyway. They can extend out several feet, but..." she paused for a moment, trying to figure out how to put her thoughts into words. "You know how if you're in a noisy crowd, you can't hear all the conversations around you at once, but you can pick out specific voices? And some voices are easier to hear in the noise than others? Well, I have a lot of trouble 'picking out' most things. I can sense what I strongly suspect is the motion of fluid in bodies. I can tell when somebody is alive and when they are not, even if I can't find a pulse. And I can get a couple of details like body temperature and soforth. But pretty much everything else is... permanently background noise, and I don't really 'see' it in any distinct way. The outer regions of an aura look... a sort of faded peach, I guess? Like a placeholder color.
"What I can distinctly perceive looks as if it sits a few inches above the body, by which I mean outside the body between me and the patient. It is solid in colour, I need to use normal sight to see through it, but because it's always moving, I can glimpse the body underneath anyway. It's like watching the sunlight on waves, I suppose. In you, it looks deep blue, which is normal for a healthy person; there are green or red tinges if it moves too... too quickly or jarringly, which can be a sign of illness if it happens excessively, although it can also just be a sign of pain or agitation. I suspect it's indicative of a physiological response in the blood or something; a small amount of that is normal. Areas over which it doesn't seem to wash, or areas where it doesn't move, are also often causes for concern. In some sick people, it is too faded, or too dull or bright. Sometimes there is variation in the brightness or vividness, with most of the blue being concentrated in the centre of the body; that's common in hypothermia patients or patients with severe heart problems. In everybody, it strengthens and weakens slightly with a pulse. Yours appeared fairly typical; a little more vivid than normal, possibly since you were not sedated. Although I wouldn't rely on my Auristics for any sort of diagnosis, if you're worried about your health."
