“Color Changes” is the phenomenon of alteration in the visible hue of an object, substance, or light due to differing conditions such as lighting, temperature, or chemical reaction. This process can occur naturally, for example in chameleons adapting their coloration to their surroundings, or be artificially induced through factors like heat treatment on gems and metals. The science behind these transformations involves the absorption and reflection of various wavelengths of light by different materials. Spectroscopy analyzes these shifts in color to discern properties of substances at a molecular level. Distinct from perceived color changes caused by optical illusions or variations in human color perception, actual color changes represent a physical alteration in how an object interacts with light.
