Did Kurt call PC "green blood"

In episode 2 of webseries if I am not heard wrong. What's meaning of green blood?

I take it to mean something like "greenhorn", which is basically noob in old Westerns.

Yea sounds like he is calling us a newbie.

I thought it might be a slightly (?) derogatory name for our merchant faction? Our noble blood?

@valla Hmmmmm actually I like that more.

@valla Why green? I mean I heard only blue blood when come to noble/royal.


Different world, different slang?
