The camouflage seems to be a mix between a blue and arctic patterns. The camouflage is best used with Arctic Spetsnaz models as it nearly matches their blue uniforms in multiplayer, thus making it harder for the opposing team to spot their weapon at times. Siberia Camouflage seems to be the closest thing to Blue Tiger Camouflage, which does not return in Call of Duty: Black Ops. The Siberia Camouflage can be seen on the Crossbow in "WMD".
