A halochromic material is a material which changes color when pH changes occur.
Halochromic materials are used for stuff :P
Halochromic compounds: compounds with different colors dependings on the pH.
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.

Methyl orange is a halochromic substance. When it binds to existing hydrogen and hydroxide ions in solution, these bonds cause changes in the flow of electrons, which in turn affects the amount of light absorbed. This is perceptible to the naked eye as a color change in the solution.
In science indicators are used for seeing weather a liquid is either a stong acid or alkailine or a week acid or aklaline or it can be neutral which is neither. You can check what it is by using a pH Scale.
