When these pigments are used to illustrate or write something, they are always visible, even in the darkness. Also, they are indelible, even with magical removal. For example, if the pigments are used to write the name of an inn, then it will be visible even in on a moonless night. Additionally, once the name of the inn is painted, it can never be removed. Even trying to paint over it doesn’t work—the paint above dissolves.
