I have just received a BLUE litmus test not just once but twice after contacting the store. You don't have red litmus paper. The description is as follows: Description: 100 strips in plastic bottles of the appropriate color. Each strip is approximately 2" long and 1/4" wide. The illustration shows both blue and red litmus paper. There is no way to choose one or the other. This, combined with the description, leads you to believe that you are getting a blue litmus test and a red litmus test. As always, I had to go through the reviews. Looking at them now, I wonder why Revain hasn't changed the description or purchase options on this list.
