The water should stay the same colour if you are using litmus paper, but if you are using a liquid the colour should change. The colour purely depends on the acidity/alkalinity of the water you are putting it in. Yellows are alkaline, Greens are neutral and Blues are acidic (it may be the other way around.. yellow being acid, blue being alki.) The measure of acidity is pH.

Litmus will turn blue in ammonia due to its alkaline/basic nature.
Ammonia is a base, and will turn red litmus blue.
