You're right, that 4th argument for FacetedTriangle isn't used and can
be deleted. Or, if you want to call FacetedTriangle with both vertex
locations and color specfications, you could revise the routine like
this:

def FacetedTriangle(self, v1, v2, v3, c1, c2, c3):
    self.vertices.append(pos=v1, color=c1)
    self.vertices.append(pos=v2, color=c2)
    self.vertices.append(pos=v3, color=c3)

Then you would say self.FacetedTriangle(v1, v2, v3, c1, c2, c3).
