Margie V. asks, "Is the pigment analysis done on
beards the same as on the petals?"
Margie, I cannot answer that based on solid
knowledge and direct experience. Chuck Chapman can, I believe, but I risk
expressing an opinion I suspect is accurate. The answer is "Yes."
Please, however, keep in mind my disclaimer.
Testing pigments in beard hairs might be rather
tricky. It means cutting off the significant portion of an awful lot of
iris blossom fall petals. The amount of tissue required for "kitchen
chemistry" is probably several orders of magnitude greater than what would be
needed for sophisticated laboratory analysis.
I suspect each of the pigments and the variations
on those pigments have unique reflected light spectra, which could be graphed or
measured electronically. I don't know if anyone is doing that, but I am
fairly sure it is possible as a method of identifying what or which
pigments are present.
We just don't have access to either the techniques
or the technicians--yet. ---At least as far as I know.
