In the animal kingdom, Rain Blue can be a warning or a disguise. Some species use bright Rain Blue markings to warn predators of toxicity (aposematism), while others use muted shades of Rain Blue to camouflage against their environment. For example, the feathers of certain tropical birds refract light to create iridescent shimmers of Rain Blue, a phenomenon known as structural coloration, distinct from chemical pigmentation.

Geologically, Rain Blue appears in rare gemstones and common rocks alike. Minerals containing specific trace elements—like copper, iron, or manganese—often exhibit stunning variations of Rain Blue. These natural occurrences have been the source of our pigments for millennia, grinding down these stones to capture the essence of Rain Blue for our art.
