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).
Red litmus paper will turn blue due to HBr. HBr is a hydrobromic acid. So therefore the paper will turn blue due to it being an acid.
