A 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.
The pH test paper that I've seen is generally a sort of pale orange or yellow color before it's used.
On the pH-paper Meck art .9565 the acidic range color is green to red-brick.
