The phrase "cabbage indicator" refers to the use of red cabbage juice to indicate the pH of a solution. For red cabbage contains the pigment molecule ka flavin, which is an anthocyanin. In fact, anthocyanin also is responsible for the reds of certain tree leaves such as sassafras [Sassafras albidum] and sourwood [Oxydendrum arboreum]. Anthocyanin has the advantage of being a water soluble pigment. Its color varies depending upon the acidity/neutrality/alkalinity of the solution in which it's found. For example, the anthocyanin pigments in red cabbage juice turn red in acidic, purplish in neutral, and greenish-yellow in basic solutions.
