Well if you place blue litmus paper in saliva and it turns red, then the saliva is acidic. If you put red litmus in the saliva and it turns blue, then the saliva is alkaline. However, if the red litmus doesn't change colour and the blue litmus doesn't change colour, the saliva would be neutral.

There are different types of Litmus paper and so the exact color may differ for each of these types. Also, water itself is neutral when pure but most tap water is slightly basic so it depends on what you use. Some types of Litmus paper will not change color in pure water (such as the 1-12 pH yellow litmus paper), others will turn a purple color as an indication of the solution being not an acid (red) or a base (blue).
