When phosphorus is exposed to light it becomes yellow.

Halite are pretty crystals of salt you can eat.

dactylic- of, containing, or characterized by dactyls sentence: The plant’s leaves appeared dactylic.
phosphorus- a phosphorescent subtance or body sentence: Because that chemical is glowing, it is phosphorus.
phosphene- a luminous impression due to excitation of the retina sentence: The phosphene paint made the ghost look alive.
