TY - JOUR A1 - Vollmer, Michael A1 - Mustard, Alexander T1 - Blue - the color of (pure) water T2 - Physics Education N2 - Water can exhibit many different colors due to a variety of physical properties. Here, we focus on some observable colors within very pure freshwater. We only treat the absorption of light due to electronic and ro-vibrational excitations and scattering due to refractive index fluctuations of the water and the respective consequences for the appearance of colors.
