Imagine I'm modeling a TTRPG figure, printed with two different
filaments, and I will dye some of the surfaces and I'm trying to
model the final product as accurately as possible.

(I chose dye because it has no thickness, so zero-thickness face
coloring is the only accurate way to model it).

not being one to argue, but colour is not 2d. (in fact, nothing in the
physical world is 2d, although it may look like it.) Dye penetrates the
object, but  argb allows translucency, sort of. But, in reality, on a
'2d surface....' you have to make compromises to get a representation of
a 3d model, colour will be one of them.

aybe make a thin surface skin of the object, or thic=k if you wish.
Maybe Minkowski or scale/difference, solid colour that. But that will be
tedious, so perhaps simpler to use some other tool, one that cheats,
maybe Blender? ;-)

Best wishes,

Ray
