Default Japanese beetles seem to have a color preference
We have a couple of shrub roses, ostensibly "Pink Grootendorst," which
manage to produce blossoms ranging in color from almost white to deep
red.

We find the beetles in the light-colored flowers all the time, and
they've pretty much destroyed any that have already blossomed, while
they leave the dark-colored flowers completely alone.
