I think Skink/Toxin/Spines looks best on the Noc! The slight darkening of chartreuse makes it look more balanced against the ginger. Spines rather than contour, because green isn't a perfect match for chartreuse. Spines are more discreet, which allows them to blend better with both the primary and secondary.

As for the PC: Woooooow the second scry! I swear, teal stained is up there as one of my favourites over warm colours. The first scry also looks nice, and yeah, would be cheaper, but stained looks SO. COOL.
