The pearl oyster, Pinctada margaritifera (Linnaeus, 1758), is one of the only bivalves expressing a large varied range of inner shell color, and by correlation, of pearl color. This phenotypic variability is partly under genetic control, but also under environmental influence. This R package allow to to delimit and characterize their color variations (by the HSV color system) with pictures.
