"Where'd that yellow pollen come from?"

Beekeepers who watch their bees return to their hives with pollen loads like to guess the origin of the pollen. Red, yellow, blue, white...

It's not unlike "What Color Is Your Parachute?" the job-hunting guide by Richard N. Bolles.

Sunday the bees foraging in flowering quince collected yellow pollen--heavy loads of pollen. They struggled with the weight and then headed home to help feed their colonies.  

Blue skies, pink flowers, yellow pollen...life is good.
