Re: Gum Calibration 2 (How to read color samples?)
Hi Loris,
Maybe but,
All my pigments are diluted 15ml to 150ml paint to gum. Any less and they get very wishy washy (insipid).

David, could it be that the pigment concentration is too much? I think the
problem lays right there. In an article by Sam Wang it was written that he
mixes his color to a saturation and luminosity close to the test patches
found in color newspaper (usually printed somewhere in the bottom or in
the middle of two pages). And I remember Katharine writing something about
this too...

P.S. Going to mix a new batch of gum (from powder) that will be used to
make stock solutions...
I will start with:
1+3 PY151 (15ml paint giving total 60ml stock)
1+5 PV19 Rose (15ml paint -> 90ml stock)
1+7 PB15:3 (15ml paint -> 120ml stock)
and dilute more as necessary.
