It would turn purple because it is used in the house. So it is a household item.
Litmus paper is a commonly used pH indicator. Litmus is a water-soluable mixture of dyes extracted from lichens. When the paper is dipped into an acidic solution, the paper absorbs a proton from the acidic solution, and it creates a new compound inside the paper that absorbs lower energy light (red light). This makes the paper appear red.
dark green
The color of the paper changes based on the acidity or alkalinity of the solution it is dipped in. By comparing the color of the paper to a pH color chart, the pH of the solution can be determined.
When dipped in coffee, pH paper will change color based on the acidity or alkalinity of the coffee. If the coffee is acidic, the pH paper will turn a different color than if it is alkaline. This color change indicates the pH level of the coffee.
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.
Shampoo is slightly acidic, If using universal indicator paper I would say light orange/yellow. This is because the acidity helps make the cuticle smoother, making the small overlapping scales on the hair lie flat.
yellow
Shampoos are lighty acidic, with a pH between 6 and 7; with the Merck pH paper art. 9565 the color can be a shade of green.
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
orange

You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
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
It stays blue.
The color become blue.
