Lightning, fire, and phosphorescent organisms all produce their own light. Additionally, many other natural phenomena lead to visible color.
How Colors Are Produced
Color can be generated in the following ways:
Color by refraction: When light passes through a refractive material, it is split in a pattern that depends on ...
