Is an indicator color change an acid or base?
depends on the indicator used. in case of red litmus... changes to blue for basesand no change in acids blue litmus - changes to red in acids, no change in bases phenolpthelin - changes to pink in bases, no change in acid methyl orange - changes to red in acids and yellow golden in bases
An indicator does which one of the following in the presence of acids and bases?
Indicators can be used to determine if a substance is a acid or a base because of the reaction that occurs between the substance and the indicator. This creates a color change in the indicator (depending on which indicator you use). If it is a universal indicator, the substance may change from deep red to violet. If it is a litmus indicator, it will only turn either red or blue.

How does litmus in the litmus milk act as a redox indicator?
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.
