Litmus paper is obtained from lichens.Litmus paper could be blue or red in colour.Red litmus paper is used to check  to whether the substance is alkaline in nature as it does not show any colour changes to acidic substances.Same way blue litmus paper is used to find whether the substance is acidic in nature as it does not show any colour changes to alkaline substances. On contact to an alkaline substance red litmus paper turns blue, the same way  goes to the vice versa.  Basicly litmus paper is  used to find the ph(potential of hydrogen) in chemistry and other fields of science and medicine.
