Optical colors refer to the colors that are perceived by the human eye when light is reflected or transmitted through objects. These colors are a result of the interaction between light waves and the molecules in the object, which absorb certain wavelengths of light and reflect or transmit others. The field of optical colors explores how these colors are produced, the properties of different colors, and how they can be manipulated or reproduced using various optical technologies. This area of research is important in fields such as optics, materials science, and color science, and has applications in industries such as fashion, graphic design, and visual arts.
