Luminous paint is a type of coating that glows in the dark after being exposed to light. It contains phosphorescent materials that absorb light energy and then release it slowly, creating a glowing effect. This paint is often used for decorative purposes, safety markings, and in art projects. Common applications of luminous paint include children's bedroom decorations, emergency exit signs, and outdoor murals. It is available in various colors and can be applied to different surfaces, such as walls, wood, and metal. The glow can last for several hours, depending on the quality of the paint and the amount of light it absorbs.
