Blue litmus paper will turn red when dipped in a solution with a pH below 4.5, indicating acidity. Aspirin (acetylsalicylic acid) has a pH of around 3.5, which is acidic. Therefore, blue litmus paper dipped in aspirin will turn red.
Litmus paper would turn blue when dipped in an aqueous solution of aspirin, indicating the solution is basic. aspirin is a weak acid and when dissolved in water, it undergoes hydrolysis releasing hydroxide ions which makes the solution basic.

Red color in acidic solutions and blue color in basic solutions.
Red litmus paper is used to test for acids. If the red litmus paper turns blue when dipped in a substance, it indicates the presence of an acid.
Litmus paper dipped in coke will turn red, indicating that the solution is acidic. This change in color occurs because coke is a carbonated beverage containing phosphoric acid and citric acid.

Blue litmus paper will likely remain blue when dipped in spinach as spinach is not acidic enough to cause a color change to red.
Blue litmus paper turns RED in an acid. Red litmus paper turns BLUE in a base.

Litmus paper would turn blue when dipped in an aqueous solution of aspirin, indicating the solution is basic. aspirin is a weak acid and when dissolved in water, it undergoes hydrolysis releasing hydroxide ions which makes the solution basic.
When a strip of litmus paper is dipped into an acidic solution, it turns red. This is because litmus paper changes color in response to the pH of the solution it comes into contact with. In acidic solutions, the paper turns red, indicating low pH.
It stays blue.
Well, isn't that a happy little question! If you were to dip litmus paper into an aqueous solution of aspirin, it would likely turn the litmus paper slightly pink. Aspirin is slightly acidic, so it would cause the litmus paper to change color in a gentle and peaceful way. Just remember, every color on that paper is part of the beautiful chemistry of our world.
