Lumin

A glowing green bottle-shaped object with a black silhouette of a person with wings and another figure inside, and the text 'Saint Cloud' and 'Chroma' at the top.

Originating from the mineral phosphorus, and observed in nature as early as 1000 BCE in both fireflies as well as glow-worms. It was first isolated in 1669 by the German physician Hennig Brand, who oddly enough was looking for gold through a (ahem) unique process. Happy accidents being what they are, he discovered a substance that had several (ahem, again) properties, including the ability to glow in the dark. Since its discovery, it has been used in countless applications. For Lumin, the exterior employs a phosphur, emitting light after coming into contact with a light source, and continues to glow. This makes our specific application a phosphorescent. The etymology of the name is derived from the Greek word, phosphoros, which meant, “bringer or light”

Green powder dispersing against a black background, resembling a spray or explosion of color.
