That is a completely ignorant statement. The color (or other properties) of a molecule (which is what water is) are not going to be the same as with the colors (or other properties) of any individual atoms that make it up. Carbon is typically a black solid (except as diamonds), hydrogen, nitrogen and oxygen are colorless gases, yet as C16H10N2O2, they form indigo dye that makes blue jeans the color they are. NO2 formed from two colorless gases is reddish-brown, not colorless. Sodium is a silver metal, Chlorine is a greenish gas, but Sodium Chloride (Salt) is white. Lead is dull gray, oxygen is colorless, but Pb3O4 is bright red-orange.
