Re: HYB: pigments - red, carotene

How would a bloom containing lycopene ever look the orange-red color of
extracted lycopene pigment?

The extracted pigment from a pink flower like PINK ATTRACTION (and
presumably all other tangerine-factor pinks?) is bright orange tomato
red, but the flower certainly isn't!  Not even in the same color range.

There are other factors (that I don't begin to know or understand) to
consider than just the presence of the pigment.

Stuff in the cytoplasm?  Stuff in the 'wrapper' around the plastid?
Chemical form of the pigment in the plastid?  Physical characteristics
of the flower cuticle?  Other pigments in the plastid?  Physical
arrangement of the plastids inside the cell (are the vacuoles and their
pigments layered on "top" of the plastids inside the cell)?
