Red litmus paper turns blue in basic conditions. the reaction of magnesium with water produces Magnesium Oxide and Hydrogen. Magnesium Oxide (Mg(OH)2) dissolves in water to form an alkaline solution. (Alkalines are a type of base)

Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation

There are different types of Litmus paper and so the exact color may differ for each of these types.

Blue litmus paper remains blue, the same goes for red litmus paper. Although the above statement says that tap water is slightly basic, the pH is still close to neutral and will not be significant enough to cause a colour change for the litmus paper.

Why does not acids burn litmus paper?
Actually, some acids do burn litmus paper. Hydrochloric acid, for example, can burn paper, but the litmus on litmus paper shields the paper from the acid. Sulfuric acid, however, has dehydration properties, and would suck the water right out from the paper, charring it instantly.
When strips of blue and pink litmus paper are put in water the paper changes?
