A universal indicator is a blend of pH indicator solutions designed to identify pH of a solution over a wide range of values. There are several different formulas for universal indicators, but most are based on a patented formula developed in 1933 by Yamada. A common mixture includes thymol blue, methyl red, bromothymol blue, and phenolphthalein.
