Actually it is both at the same time:
weakly acidic in fully protonated (compound formula H+PPT), no color, pH < 8
and
weakly base when deprotonated (PPT), with blue-purple color at pH > 8 - 10
In acid conditions it is colorless and in basic conditions it is pink and then bright red
No, phenolphthalein is colorless in acidic solutions. It turns pink or red in basic solutions.
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.

Phenolphthalein is a pH indicator that turns pink in basic solutions, and colorless in acidic solutions. Normal pH of saliva ranges between 6.2 (acidic) and 7.4 (basic), with 7 being neutral pH. So, the answer is, "it depends." Is the saliva acidic, or basic?

Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.

Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
if concentration is particularly strong then it became purple
Yes, bases turn phenolphthalein pink because phenolphthalein is colorless in acidic solutions but turns pink in basic solutions with a pH around 8.2 to 10.
The color of phenolphthalein after the addition of dilute HCl is colorless. Phenolphthalein is typically pink in basic solutions but turns colorless in acidic conditions due to the change in pH.
