Structural color in wax bloom produces blue appearance on fruits across a wide phylogeny: (A) undamaged highbush blueberries growing on the plant; (B) blueberry with (i) unmodified wax, (ii) mechanical wax removal, (iii) chloroform wax removal, (iv) surface application of (almost) index-matching oil, (v) surface application of water, (vi) outer skin peeled to reveal flesh, and (vii) underside of peeled skin; (C) transmission optical microscopy of peeled blueberry skin from internal edge showing red pigmentation in epidermal cells. Scale bar - 200 μm; (D) (i and ii) a selection of plum (Prunus domestica) fruits with different cell pigmentation, (i) with wax intact and (ii) with wax removed.
