No, it is NOT an indicator of a chemical reaction. Change in color IS an indicator of chemical change, though.
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
The color purple is a physical property, but if it appears during a chemical reaction, it is representative of a chemical change.
Generally, you know a chemical reaction has occured if there is a change in temperature, a change in color, a formation of a gas (bubbles), or any kind of flame.
No, it is not true.

The change of color may be a sign of a chemical reaction.
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
Yes it is chemical change.

Change of shape can not be used to indicate a chemical reaction has happened. Examples of evidence of a chemical reaction are changes in odor or color.
Evidence of a chemical reaction include the following: formation of a precipitate formation of a gas change in temperature change in color
Yes, the signs of a chemical reaction are: gas, precipitation, heat, color change
Change of color.
