So the second I put on the Chalcedony shader, I knew I had a keeper. Why? Well, it uses the same color palette that Gulf Racing uses for its livery. As a big fan of the original Ford GT40 (the car in the attached picture) I couldn't resist, and given that the Crucible is Destiny's "sporting event" of sorts, I feel a shader like this fits perfectly. It's on my Titan, if anyone wants a look.
