Hi Joel.
I do not collect pollen, hence I am not experienced with the fine
details of pollen. From my limited observations, I would like to suggest
the following:
One source of green pollen can be from sunflowers.
Black pollen could be pollen that has undergone oxidation.
I'll watch for opinions from fellow contributors.
Best regards.
