Quote - My goal is a newly sculpted look (i.e. how the Parthenon would've looked in its heyday).  Once I perfect that, I might try my and at a more aged version for ruins.

Not many people are aware that the Parthenon, along with other well-known ancient Greek monuments and statues, was not just white marble in its day.  Most times plant-based dyes were used to paint statuary and structures.

Of course there is something to be said about the minimalist white under a glaring sun and juxtaposed with the blue sky and sea that Greek islands have adopted as an aesthetic image.  However, ancient peoples loved colour and used it extensively (e.g. the Minoan Palace at Knossos)

The painter Lawrence Alma-Tadema has portrayed how the Parthenon may have looked as it was being constructed in this painting:

Historical facts aside, I prefer the white marble myself and BB's shader is the closest approximation I have seen.  It worked wonderfully for my Winged Nike here:

Ok, enough of the history lesson and the profusion of links :)
