It depends on the reagent used, but most of the time the more acidic the substance is, the brighter yellow it shows up on the scale when a sample is tested for pH, while strong bases are usually deep blue.

What do you know about the pH scale?
The pH scale is a physics scale that measures the pH balance of something (obvious). It ranges from 1-14, 1 being the most acidic and 14 being the most basic. Water is neutral at 7 pH. A common acid is vinegar and a common base is bar soap. The pH scale is a scale designed to determine the acidity or basidity of a given substance and ranges from 0-14 with 7 being neutral, a substance that is between the range of 0 and 7 determines the acidity of a substance with 7 being neutral and 0 being extremely acidic while the range 7-14 determines the basidity of a substance with 7 being neutral and 14 being extremely acidic. It can be said that the acidity or basidity grows stronger the farther it is from 7.
