What color is water?
Pure water without any impurities or additives is actually colorless. This is because water does not absorb or reflect any particular color of light, which means that all wavelengths of visible light pass through it without being affected. However, when light passes through a large body of water like a lake or ocean, it can appear to be blue or green due to the way that water molecules absorb and reflect light. This is why bodies of water often appear to be a different color depending on the lighting conditions and the surrounding environment.
