In nature, color can be imparted to a feature either by a pigment or a structure that selectively reflects a part of the visible spectrum. The latter is called structural color, and it may be brighter than a pigment. Structural color is often used by animals for signaling, mimicry, and/or mate choice. In plants, mainly fruits, structural color is probably used for mimicry. Silvia Vignolini, Paula Rudall, Alice Rowland, Alison Reed, Edwidge Moyroud, Robert Faden, Jeremy Baumberg, Beverley Glover, and Ullrich Steiner described the anatomical arrangement within the outer layers (epicarp) of a blue fruit found in equatorial Africa that results in a blue color more intense than that of any previously described biological material! Although this fruit (Figure 1) has no nutritional value, by imitating the appearance of a fresh nutritious fruit, it avoids the energy cost of producing pulp yet can be dispersed by birds. And not only can it imitate a food source, it is probably also dispersed by birds who use it to decorate their nests in order to attract mates.
