It makes it red.
Acids turn litmus paper red. Bases turn litmus paper blue. If the paper turns orange, its an acid.
A weak acid is a acid with a pH scale just below 7. The closer to seven the weaker an acid it is, a acid with a lower number is a stronger acid then an acid with a higher number. (no acids have a pH above 7)
weak acid = orange/yellow
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.
It depends on the base used. For strong acid vs. strong base, phenolphthalein can be used as indicator. For strong acid vs. weak base, methyl orange can be used as indicator.

Indicator is a process which is used to find out the substanceis acid,base and salt. example: litmus paper and termuric both are natural indicator. example of artificial indicator: mithyl orange and phenolphtaceil
All acidic solutions are colourless in phenolphthalein, pink in methyl orange solution and turns blue litmus paper into red.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
