Colors of Visible Light. Within the narrow band of visible light, the different wavelengths are perceived by people as different colors. The shortest wavelengths are perceived as violet and the longest wavelengths are perceived as red. There are seven wavelength ranges within the visible spectrum that each correspond to a different color. The colors fall in an order commonly referred to with the acronym ROYGBIV. ROYGBIV can aid in remembering the order of the colors: red, orange, yellow, green, blue, indigo, and violet.
