Definition of color
Color is defined as the visual perception of different wavelengths of light. It is the result of the interaction between light, the eyes, and the brain. Colors are perceived due to the way in which different wavelengths of light are reflected or absorbed by objects. The human eye possesses specialized cells called cones, which are sensitive to different wavelengths of light and enable the perception of colors. Colors can also be defined in terms of hue, saturation, and brightness.
How color is defined
Color is defined by the way in which different wavelengths of light are absorbed or reflected by an object. When white light, which consists of various wavelengths, strikes an object, certain wavelengths are absorbed by the object while others are reflected. The wavelengths that are reflected are then detected by the cones in the human eye, and the brain interprets this information as color. Every color in the visible light spectrum corresponds to a specific wavelength, with red having the longest wavelength and violet having the shortest.
