Spectral Colors: the wavelengths of white light (i.e. the visible spectrum, that’s to say that portion of the set of electromagnetic radiations emitted by the sun, comprised between 400 and 800 nm) discernible at naked eye as separate colors (hues) (red, orange, yellow, green, blue, indigo and violet) whenever the white light passes through a prism (hence also the name of Prismatic Colors).
