The colour of water and ice is, intrinsically, a very slight blue hue, although water appears colourless in small quantities. Ice also appears colourless, and water vapour is essentially invisible as a gas. Water is constantly in contact with the ground in which it stagnates or circulates, so equilibrium develops between the composition of the soil and that of the water.
