Blue iridescent berry, no blue pigment

Blue African fruit of a plant plant Pollia condensata contains no blue pigment. The blue and its iridescent shine are caused by a Bragg reflection - intense peaks of light generated at certain wavelengths and angles - created by spirally stacked cellulose fibers that form multiple layers in the fruit's skin.
