Quick question on this.

At low pH : Acid/H+ reacts with A– AND equilibrium (position) shifts towards HA (to give a red colour)

At high pH: Alkali/OH– reacts with HA/H+ AND equilibrium (position) shifts towards A– (to give a yellow colour) 

1. This is a buffer right? Instead of saying it moves to A- on the second one can you say equil move to increase H+ concentration?

Indicators are weak acids and weak acids by themselves are buffer so yeah.
