nocturne (concept) by francine leclercq from usa

Concept

Creation of two similar colors in tint, one composed of phosphorescent pigment for invisible daytime graphics, shapes that would be revealed at night.
“Glow in the dark” or phosphorescent pigments consist of very fine crystals of zinc sulfide. Copper is added to the zinc sulfide as an activator. This allows the crystals to absorb light and slowly emit it over time. The slow emission is called phosphorescence lasting up to 12 hours.
