=it would go darker, so maroon or brown, hope that answers your question!=
Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
The answer isn't so simple. There are various kinds of pH paper. However, I presume you are referring to litmus paper which is the widest distributed form. Acetic acid has no effeect on red litmus paper but turns blue litmus red
Litmus paper: red color in acidic solutions and blue color in basic solutions.Phenolphthalein: no color in acidic solutions.
red
When red litmus paper is dipped in distilled water, it will remain red, indicating that the water is neutral and does not change the acidity. Similarly, when blue litmus paper is dipped in the same distilled water, it will also remain blue. This observation confirms that distilled water has a neutral pH of around 7, which does not affect the litmus papers' color.
If if it is red Litmus paper, then it will remain red because vinegar is acidic. (Blue Litmus paper would turn red if you dipped it into vinegar).

red PH paper will get more darker when dipped in vinegar because vinegar is acidic in nature.it contains acetic acid& it's PH is always less than 7 depending upon concentration of acetic acid present in vinegar.

Blue litmus paper turns red in vinegar solution because vinegar is acidic and pH below 7. The acidic solution causes the blue litmus paper to undergo a color change and turn red.
I think smoke turns limus paper red and blue i'm not sure
The red litmus paper will turn blue when dipped in hydrochloric acid. This is because hydrochloric acid is acidic, and acids turn blue litmus paper red.
It turns red because rainwater is slightly acidic and litmus turns red in the presence of acids
Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.

Turns red.
If the vinegar is strong enough to be below 4.5 pH the litmus paper will turn (or stay) red.
