Chris, you may wish to inspect stored pollen more carefully, since if you
are only looking a the surface layer in each cell, then you will only see
one color.  If you take a 5mm diameter pipette tube and shove it down into
pollen cells, you can pull out a plug of the stored pollen.  What I find is
that there are often multiple layers of different colored pollen in the same
cell.
