UI Confusion (Humours/Food)

Hey guys 
I'm a very new one around here and try to comprehend Salem. But there is a bunch of confusion around the attributes of my character and food. I want to make sure, that I understand this right. Maybe the confusion is based on something I messed up with the alternative client or I'm just a bit to used to other games to get it right here.
So... just to be sure that I get it correctly:
The blue food stat (mercury) is for phlegm (black bar), correct?
The other food colours are related to their same coloured humours right?
If the blackbar is phlegm, then the green bar is black bile?
The tooltipp of the humours is quite confusing too.
May I ask why black bile is green? Appears obvious to me to give it the black bar... and why phlegm is grey but related to a blue food attribute? Why not turning the blue food attribute grey?
