A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Normally, the indicator causes the colour of the solution to change depending on the pH.
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.
Red/pink for litmus indicators. Other indicators such as methyl orange will display different colours.

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.
