In a basic medium phenolphthalein changes color frompink to colorless.
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 and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
Phenolphthalein is pink in a basic environment.
In acid conditions it is colorless and in basic conditions it is pink and then bright red

Phenolphthalein is a chemical compound with the formula C20H14O4. It is coloured, and the colour changes in relation to the acidity of it environment. It turns colorless in acidic solutions and pink in basic solutions.
Any colour appear.
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
Phenolphthalein turns pink in a base and turns colourless in a base

Phenolphthalein is an indicator that undergoes a colour change from colourless to pink that begins at a pH of 8.0. So in the titration your performing the phenolphthalein will start to change colour at the point when the moles of acid equal the moles of base. Although this colour change occurs at a pH of 8.0 and not at a pH of 7.0 phenolphthalein is commonly used because of the distinctive colour change that occurs. Phenolphthalein is colourless in acids and pink/purple in base. It also turns orange in very strong acids.
