The color of Ph paper is supposed to change, depending on the Ph level of the liquid you placed it on. The color is dependent as well. When purchasing Ph paper, it comes with a guide on the box. It is best to use that.

∙ 13y agoA non used pH paper has a color which depends of the producer. Example for pH-box paper from Merck: brick red for basic, yellow for neutral, blue for acids.
In bases or acids the color is changed; to identify the pH of a solution with a pH paper compare the obtained color with colors on the box label.

in neutral solutions ph paper turns to blue!
pH paper contains pH-sensitive indicators that change color depending on the pH of the solution it is dipped in. By comparing the color change of the pH paper to a color chart provided with the paper, the approximate pH of the solution can be determined.
