Tyndall effectDermatology The change that light undergoes as it passes through a turbid medium–eg, skin, causing the colors of the spectrum to scatter; colors with a longer wavelength–red, orange and yellow tend to continue traveling forward while those with a shorter wavelength–blue, indigo and violet scatter to the side and backward; the TE explains why a subcutaneous lesion, which should have a red-brown hue due to hemorrhage or melanin deposition, has a blue tinge
