The litmus paper contains a material called indicators in chemistry. The speciality of the indicator is that it can react with an acid (H+) or a base (OH-). The product when an indicator reacts with an acid will have one colour and when it reacts with a base, it will have a different colour.
When a litmus paper is put in a solution, depending on what the solution is, the indicator will react with the solution and will change its colour.
