Which of the following is not a component of a pearl's color?

Explanation:
The color of a pearl comes from three elements: the bodycolor, which is the underlying hue of the pearl; the overtone, the subtle secondary color seen over the bodycolor; and orient, the internal glow or iridescence produced by light interacting with the nacre layers. Luster, while important for how bright or shiny the pearl appears, is a surface quality rather than a color component. It affects how color is perceived but isn’t itself a component of the color definition. So the item that isn’t a color component is luster.
