The papers do react to pH, don't get me wrong. If you dip them in vinegar they will turn red, if you dip them in borax they will turn blue. Problem is, if you're trying to measure anything that isn't a strong acid or base, the colors in the middle around neutral aren't different enough to tell! Especially for slightly acidic things, colors 4-7 are nearly identical. The product page image is taken in a white-box with bright white lighting, making the colors easier to read in the photo, but in real life under normal lighting conditions, colors 4-7 look like the same shade of dull yellow and are indistinguishable from the default neutral color of the paper. So basically, these are about precise enough to tell you that it is either an acid OR a base, but not an actual measurement, especially when close to neutral.
