👉 Heterochromic is a term used in physics to describe objects or materials that have two different colors, such as red and blue. This can be seen in a spectrum where all wavelengths are present at the same intensity but are not of the same color. For example, a red light with a wavelength of 550 nanometers (nm) would have both red and blue components. The term is often used to describe materials that are not homogeneous or have a specific color distribution.
