A universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 0 to 14 (it may be negative or higher depending on the concentration) to indicate the acidity or alkalinity of solutions, where 7 indicates neutral.

PH papers are paper infused, or saturated, with pH indicators or more frequently, a mixture of indicators. They are used to test for alkaline or acidity of a solution or substance such as soil. pH papers are usually sold as strips. These strips of paper (or sometimes fabric) change color when they come in contact with the material or solution being tested.
Often, indicators are mixed to create something called a universal indicator, which can change to several different colors to indicate a wide range of acidity; usually from pH2-10. Most pH paper strips are impregnated with universal indicators.
