Perhaps that is why Hansa yellow is used now instead of other yellows as it
is semi-transparent.
I feel kind a dumb I just didn't ask you direct on the carbon list. I
forgot you had done color carbon yourself. And then I tend to get confused
a lot nowadays. Damn I don't even remember the 60's and I think I was there.
