Yeah, there was painfully bright yellow flare with boro during class. I haven't yet tried color in that way at home. I'm finishing up some studio construction but wanted to make sure my EX-20 was working. Boro melts but I can't tell if my O2 is above 90% like it should be. The color test is next and I will report back for those who are interested.
