Wiki - The Joy of Painting
Just to the southwest of the Pomona's Farm moongate is a small tent inhabited by the great Bob Ross and his business partner, Walk Kowalski.
Here, would-be painters can buy their supplies but the brushes used to create the most beautiful paintings in all of Sosaria must be earned by performing a quest for Bob.
Bob requires seven natural dyes to create the only paints he's ever used. Bring those to him and receive a brush and pallet, which are single-use tools that will allow you to paint a masterpiece.
The Joy of Painting Quest can only be completed once per week.
Besides the brush and pallet, blank canvasses, paint, and gloss are required to paint a painting. Walt Kowalski, Bob's supplier sells these objects in the same area where Bob practices his art.
