Elias Garcia Martinez's Paintbrush Set

Origin
The Ecce Homo (Behold the Man) in the Sanctuary of Mercy church in Borja, Spain, is a fresco painted circa 1930 by the Spanish painter Elías García Martínez depicting Jesus crowned with thorns. While press accounts agree that the original painting was artistically unremarkable, its fame derives from an attempt to restore the fresco by an untrained amateur in 2012. Cecilia Giménez, in her eighties, was allowed by a priest to restore the humidity damaged painting. Lacking any art skills, her touch up damaged the painting but was regarded as comic, morphing Christ into a tunic-wearing monkey.

Effects
Any works painted by this set of brushes and a pallet will become bonded to the original vision, and resist any attempts to alter them by interfering with the part of the human brain that processes artistic talent. On their own, they do nothing of note, but they will continue to seep black paint until all three are reunited with the pallet.
