WebBlack absorbs almost all light energy, so its reflectance curve is flat and approaches 0% reflectance. A mid-range gray, made by combining equal portions of white and black, is represented by a straight line at 50% reflectance. Other colors spike near the part of the wavelength range that is most reflected.
