Someday I'm going to paint my 67 HOK Ultra Orange, if I ever get around to it. Seems like it's going to take forever. Here's a few links I found where people used it:
This '69 Camaro looks amazing in a variant of Tangelo Orange. I spoke to them prior to painting my current project and they wanted $750 a gallon to sell me thier custom mix.
This is the PPG "Oh So Orange" The nice thing about this is it's only a 2 stage paint. Easier to repair than a true candy. (solid orange base with the metallics in the clear)
