"Panzer Colors" with #2 and #3 and "Tiger in Action" by Squadron Signal, and "The Tiger Tanks" from Osprey Vanguard are all good with many Tigers in action on all fronts. All show unit markings which would be critical in matching your color scheme with your tank.
Don't get hung up on exact colors, as there were many variations in colors due to materials used to mix the paint issued. Panzer grey was fairly uniform as they came from the factories with the designated paint. Panzer Yellow is a good base for Russia but was also varried in shade. Panzer Yellow for the Afrika Korps was lighter, but then was always covered in a coat of yellow dust which made them all look alike. Camo patterns were definately different from France, southern Germany to the Balkans and Russia.
