"Light is the energy that our eyes detect when we see. When there's no light, we won't be able to see anything even if there is nothing physically wrong with us. Light may differ in color, brightness and purity. Color is dependent upon the wavelength of light. Low-frequency light, or light with longer wavelengths, is reddish; while high-frequency light, or light with shorter wavelengths, is bluish. The brightness of light, on the other hand, is measured by the wave's amplitude. High-amplitude light waves are brighter than low-amplitude light waves. Lastly, purity or saturation is measured by the amount of white light added. Pure light has lesser added white light than saturated light."
Even black and white are still colors. Then, is there a thing that is colorless?
