Litmus paper is used for measuring the pH of a liquid. The pH is a measurment of how acidic/basic a liquid is. Red/Blue litmus paper contains a compound that changes colors at a certain pH. There are a variety of different litmus papers you can buy which each change colors at a specific pH. Generally, red is associated with an acidic solution (pH < 7) and blu with a basic solution (pH > 7). By dipping a litmus paper in a solution and watching for a color change, you can determine if the pH is below/above a certain threshold
