Re: OT: Pigments & green (was Silverado)

despite Dave's claim that he's not an expert I think he actually 'got' what
I was thinking when I said a combination of dosages might help to create a
green iris.

First, let me say that no one has said anything in this string or anywhere
else that I remeber reading about a dosage actually having anything to do
with yellow expression, so I was basing my thought string on information
that I do not have.

Having said that Patrick did suggest that a 'light wash' [of
anthocyanin-blue/green/violet pigment if I'm interpreting this correctly]
might result from 3 doses of "I".  In addition Kieth Keppel suggested that
some 'colors' are the result of different pigments being expressed so close
together, but side by side that our human eyes cannot distinguish between
them, and therefore our brains interpret them as a new color.

Now, I do understand that the 'green' in iris that we have already seen is
just chlorophyll, especially when we are speaking of Iris with green near
the midrib.  I have thrown these iris and that shade of green (which I am
assuming is essentially the same color as the iris folliage/pods) out of
this particular bath water.

ThusI am suggesting that non clorophyll range of green is possible, by some
combination of the human vision capacity, the "I" factor, and the adjacent
placement of color on our iris's petal.

As I said, that hypothesis was based on an assumption which I don't know to
be true, that yellow expression is modulated from pale to bright to gold by
something similar to the dosage factor expressed in "I"

So, someone help me fill in this theory.  First someone has to tell me what
"I" actually is short for.   And what exactly is the Progenitor-derived
inhibitor? Is Progenitor a named iris? or is Progenitor-derived a
discription of how this inhibitor works?  What is the name of the yellow
pigment? Is that the same pigment as produces pinks? (y'all keep lumping the
yellows and pinks together)  What do we know about yellow expression?
