Yes. There are many different types of indicators that change colors at different levels of pH. While it will depend on you concentration of base. You can use it indicate if a solution is basic, and narrow down the actual species in solution.
No, an indicator's reaction in acids and bases is a physical change. Indicators change color based on the pH of the solution they are in, but the chemical composition of the indicator remains the same.

Substances that dissociate into hydroxide (OH-) ions are classified as bases. These bases are capable of accepting protons (H+) in chemical reactions.

A pH indicator changes color depending on the acidity or basicity of the solution it is in. In an acid, the indicator will have one color and in a base, it will have a different color. By observing the color change in the pH indicator, one can determine whether the solution is acidic or basic.
A substance that turns universal indicator green is a base. Bases have pH levels higher than 7, which causes the universal indicator to turn green.
Sorry, but that type of information is classified.
