It's impossible to say what color a detergent solution will turn pH paper without knowing more about the specific detergent. Here's why:

* Detergents vary greatly: Detergents can be acidic, basic, or neutral.

* Additives influence pH: The pH of a detergent solution can be affected by the specific chemicals added to it, such as fragrances, softeners, and enzymes.

Here's a general idea:

* Acidic detergents: Turn pH paper shades of red or orange.

* Basic detergents: Turn pH paper shades of blue or green.

* Neutral detergents: Turn pH paper a pale yellow or greenish-yellow, which is the color of the pH paper itself.

To determine the color of a detergent solution on pH paper, you need to know the specific type of detergent and its ingredients.
