I have a player interested in running an artist - preserver/smuggler build. I came up with some paint prices based on the FR Catalog. If anyone wants to add anything or comment, have at it.
blue, Balic - 12 oz. - 3 cp
green, Raamish - 8 oz. - 5 cp
ocher - 12 oz. - 2 cp
purple, Tyrian - 6 oz. - 1 sp
red - 12 oz. - 2 cp; 5 bits
yellow, Urikite - 12 oz. - 2 cp; 3 bits
vermilion - 6 oz. - 8 cp
white - 12 oz. - 3 cp; 6 bits
black - 12 oz - 2 cp
Brushes: small, 3 cp; large 4 cp
Charcoal sticks (10 pcs), 7 bits
Note that paper prices are expensive when available - and can be used to argue that the holder is literate or possibly a spell caster. More common painting mediums would be on stone, painting statues or statuettes or even walls, murals, graffiti, etc…
The Raam green is a leaded or arsenic based paint (a nod to the City State’s general insanity). Don’t chew your brushes.
