Re: HYB: pigments - mystery solved!

Lessons in specific gravity.....

Results of careful measuring of alcohol <without> adding water, then
adding carefully measured equal volume of oil results in the <alcohol>
rising to the top of the mixture, with the blue pigments in the <top>
alcohol layer.

Then adding water mixes with the alcohol and the <oil> rises to the top
of the mixture, with the blue pigments in the <bottom> alcohol-water
layer. In other words, the layers reverse.

Results?  <NO> oil soluble pigments in IC-1.

Donald, I have a lot of the test subjects in bloom right now, and some
are bug eaten, so don't mind sacrificing part of a fall.  IC-1 fades as
it folds so it would take more petals to get much pigment

Betty, I only have one bloom on IMMORTALITY open right now.  I don't
think it has any pink pigment expressed, but somewhere got the idea that
it carries pink/yellow (capacity to make pink in descendants).
