"At a dinner party, or in the schoolyard, the question of favourite
colour frequently results in an answer of “blue”. Why is it that humans
are so fond of blue? And why does it seem to be so rare in the world of
plants and animals?
We studied these questions and concluded blue pigment is rare at least
in part because it’s often difficult for plants to produce. They may
only have evolved to do so when it brings them a real benefit:
specifically, attracting bees or other pollinating insects.
We also discovered that the scarcity of blue flowers is partly due to
the limits of our own eyes. From a bee’s perspective, attractive bluish
flowers are much more common."
