When using an indicator in a titration, the color changes happen when the titrant has reacted with all the substance of interest in the sample. As soon as the titrant isn't reacting with the sample any more, it starts reacting with the indicator, and continuing past the first hint of color will be using too much titrant, and the calculations for the concentration of the sample will be wrong.
Phenolphthalein starts out pink, but will turn red as the pH keeps changing as you go further past the endpoint of the titration.

What is a negative reaction for Benedict's?
A negative reaction for Benedict's test would be no color change or a very faint color change after adding the Benedict's reagent to a sample containing reducing sugars. This would indicate that there is a low concentration or absence of reducing sugars in the sample.
What isphenolphthalein indicator end point?
Phenolphthalein is an acid-base indicator that changes color at a pH range of approximately 8.2 to 10.0. In acidic solutions, it remains colorless, while in basic conditions, it turns pink. The endpoint of a titration using phenolphthalein is reached when the solution transitions from colorless to faint pink, indicating that the pH has moved into the basic range. This color change helps determine the completion of the reaction between the acid and base being titrated.
