Anthocyanins are versatile and plentiful flavonoid pigments found in red/purplish fruits and vegetables, including purple cabbage, beets, blueberries, cherries, raspberries and purple grapes. Within the plant they serve as key antioxidants and pigments contributing to the coloration of flowers
pH indicators change their color according to the pH of a solution.
They are called pH indicators.
Indicators are used frequently for testing pH; but many other indicators exist for other compounds or ions.
pH indicators change the color depending upon acidity or basicity.
Indicators can also be prepared from plants. The red, purple, and blue colors of most plants indicate the presence of an organic substance called anthocyanins. The purpose of putting alum is to retrieve the anthocyanins present in plants.

most pH indicators are polar, whereas turps is non-polar so it doesnt mix well

There are a variety of indicators used to determine change in pH. Different indicators change during certain ranges of pH. For example, phenolphthalein turns from clear to pink in a basic solution (approximately 7.8 to 9). There are universal indicators that cover the whole pH scale.
Indicators are used to tell a person whether or not a chemical is present or what pH a substance may be. Usually an indicator is a strip that is dipped into the substance and will change color based on the presence of a substance or pH.
Indicators :)
Indicators are substances sensitive to different ranges of pH.
