A few weeks ago I saw a screenshot from someone who did a horrific. On the right side of the screen he had a window identifying the pots.
I haven’t been able to locate this addon and I don’t have the link to the screenshot. I’ve also checked wago for such an aura - no luck. I should be able to make a clumsy aura for it though. But this one looked pretty neat imho.
I hope that’s what you seek because I like to give the helpful answer (I checked the pictures, the colors and effects of the different potions are shown as I think you wanted).
But in the meantime I hope that’s not it because I typed “horrific vision potion aura” on google and picked the first link and well, you said you searched !
