Without knowing where your path came from, or quite what 'ringed look' means, my
suggestion might be useless to you, so apologies in advance!

However, in this situation I think I would seriously consider building this as a
mesh, creating a ring of triangles for each point of the path. Triangle rings
can be given different textures, either picked from a list (mesh2), or UV-mapped
from a gradient of your pigment 'space'. Parsing might still take some time, but
I would think rendering would be pretty fast.
