Guild Wars 2

I have all the Jars of Paint except Purple, I have the paint brushes, and I have the canvas’s. However, when I go to the scenic vantage points and click to interact, I don’t get the item I am suppose to get….Red Color Study, Orange Color Study, etc….

The reason I don’t have the purple paint is because I have farmed 75 Coral and have not received one Vial of Manganese Dioxide…..

Hmm I did pretty much exactly the same. Didn’t run into any issue.
