Works as Described
Yes, these tablets are certainly purple.  I only need to use half a tablet at a time.  Best to use them at night - your lips and tongue will be the color of Barney the dinosaur for quite some time after use.  Helpful and necessary for those who practice self-dentistry; use them before brushing, water flossing or polishing, and they'll show you what to work on.
