Pure water is nearly colorless. However, it does absorb slightly more red light than blue, giving large volumes of water a bluish tint; increased scattering of blue light due to fine particles in the water shifts the blue color toward green, for a typically cyan net color.
Cyanide derives its name from Prussian blue, a blue pigment containing the cyanide ion.
