Quick answer
To identify pollen by color, compare the sample in consistent light, note the date and location, list plants currently in bloom, and use color only to narrow the candidates. Confirm the result with plant observation, pollen microscopy, or another identification method when certainty matters.
Use Color as One Clue
Pollen color is most useful when it narrows a list of possibilities. It should not be treated as a stand-alone identification result.
Compare color with bloom timing, plant abundance, location, weather, and whether bees are visiting the suspected plant.
Why Color Varies
Pollen can darken or lighten with age, moisture, mixed loads, and lighting. Digital screens also display colors differently.
