Yeah, not trying to butt in or sound like a bitch but I don't think diagnosing @EJCC's temperament based on how you think the 16 types fit into the temperaments as a whole. I don't think being one type in MBTI (in this case, ESTJ) necessarily proves that you're a certain temperament (in this case, pure Choleric) in the Four Humors.
Starry is one of them. I don't mean to mistreat you.
Anyway, I can see why you'd think you'd be Choleric (any ETJ would really ). I'm not too well-immersed in this theory so don't take what I say too seriously but the only Choleric traits I seem to see in you are being task-oriented, ambitious, leader-like, and respectable. But, from my personal experience with you, the qualities of yours that seem most prominent to me are being calm, patient, peaceful (you know, that whole soft and welcoming vibe that comes with being so/sx like @skylights), and reasonable. I'm friends with an ESFJ 1w2 sx/so who's probably Choleric-Sanguine and she's much more quicker to snap on you, more impatient, and definitely less peaceful - she really has little regard for her own sense of peace. Comparing you two, I definitely see more Phlegmatic in you.
Again, not very well-researched on this theory besides the basics so that's my view.
But I think it's nice to note that I think confusion between Choleric (hot and dry) and Phlegmatic (cold and wet) would probably be a good thing, because it could indicate balance in yourself as an individual. I think that was kind of the goals of this whole thing right? To try to not be exclusive to hot/cold or wet/dry and find balance in yourself (and your diet, I think - I got more info on this from my History & Culture of Food class).
I'm totally Sanguine it's not even funny.
