This depends on the indicator :
Solution of red cabbage, or rose flower, strawberry, or cherry.These turn lighter(yellowish) in the presence of an acid, and more darker(violet) in the presence of a base.
-Phenolphtaline : Remains colour-less in the presence of an acid, and violet in the presence of a base.
-Red/Blue Litmus Paper : the RLP turns blue in the presence of a base, and the BLP turns red in the presence of an acid.

What turns lithmus blue?
Acids turn litmus blue. Litmus paper is a pH indicator that turns red in the presence of acids and blue in the presence of bases.
What is an indicator used to detect an acid or base?
An indicator used to detect an acid or base is a substance that changes color in the presence of acids or bases. Examples of indicators include litmus paper, phenolphthalein, and universal indicator solution.
What is recreation of indicator with acid and base?
Recreation of an indicator using an acid and a base involves mixing a colorless or faintly colored acid-base indicator with an acid to make the solution acidic (and change color) and then adding a base to neutralize the acid and return the indicator to its original color. This process demonstrates the reversible nature of acid-base indicators and how they can be used to visually indicate the presence of acids or bases in a solution.
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

What does a sodium hydrogen carbonate indicator do?
A sodium hydrogen carbonate indicator is used to test for the presence of acids. It turns pink in the presence of an acid and yellow in the presence of a base. This color change helps to determine whether a solution is acidic or basic.
What is the reaction of methyl orange to base?
Methyl orange is an acid-base indicator that changes color in the presence of acids and bases. In basic conditions, such as with a strong base like sodium hydroxide, methyl orange will turn yellow or orange.
What are substances which exhibit a specific color in the presence of acid or base?
an indicator
What is a substance that turns blue in the presence of a base starts with r?
One substance that fits this description is red cabbage indicator. In the presence of a base, the red cabbage indicator turns blue due to a change in pH.
What is an indicator as related to an acid and a base?
It is a substance(chemical or natural) which changes colour in the presence of an acid or base.
An indicator does which one of the following in the presence of acids and bases?
An indicator is a substance that changes color in response to changes in acidity or alkalinity (pH). In the presence of acids, indicators change color to indicate acidity, and in the presence of bases, they change color to indicate alkalinity. This color change helps to visually determine the pH of a solution.
