PARACHROMATISM Meaning and
Definition
-
Parachromatism is a term used in the field of optics and color theory to describe a phenomenon related to the perception of colors. It refers to the tendency of a substance or material to exhibit slight changes in color when viewed under different lighting conditions.
When an object appears to have different hues or shades when observed in various lighting scenarios, it is said to have parachromatic properties. This effect is commonly observed in certain minerals, gemstones, and pigments that possess unique structural or chemical properties.
Parachromatism occurs due to the interaction between incident light and the molecular components of the material. The structure and composition of these materials can selectively absorb or reflect light of different wavelengths, resulting in a variation in perceived color.
For instance, a gemstone may exhibit a different color under natural daylight compared to artificial indoor lighting. This is due to the specific wavelengths of light that are absorbed or reflected differently by the gemstone's molecular structure in each lighting condition.
Parachromatic effects can also be observed in photography, where color films or digital sensors may reproduce colors differently depending on the type and intensity of the light source used during image capture.
In conclusion, parachromatism is the property of a substance or material to exhibit changes in color perception under various lighting conditions due to the interaction between incident light and its molecular structure.

Etymology of PARACHROMATISM
The word "parachromatism" is a combination of two Greek roots: "para" and "chroma".
1. "Para" (παρά) means "beside" or "beyond" in Greek. It is often used in English words to indicate something that is alongside or related to something else, but not necessarily the same.
2. "Chroma" (χρῶμα) means "color" in Greek. It refers to the visual property that differentiates objects based on the wavelengths of light they reflect.
Combining these two roots, "parachromatism" refers to a condition or phenomenon that exists alongside or beyond ordinary color perception. It typically implies a visual abnormality where colors are perceived differently than they would be by individuals with normal color perception.
