Porsche GT3 - Irish Green

Irish Green is one of the old Porsche colours - a deep green with a slight blue lean that goes back to the air-cooled cars and comes back through the factory's bespoke paint programme. Put it on a GT3, which is naturally aspirated, high-revving and built around a track, and you get a car that looks restrained standing still and isn't.

Dark greens are among the hardest finishes to film. In shadow they behave exactly like black: the car collapses into a silhouette and the body lines disappear. Give the same panel a direct highlight and it goes almost fluorescent. The band where the paint actually reads as green is narrow, and indoors that band is set by where the car is standing relative to the rig, not by the time of day.

It's the opposite problem to the pink GT3 in this same library - same car, same badge, two colours that need completely different treatment to look like themselves. Which is the argument against having one lighting setup you use for everything that rolls in - the room is fixed, so the only things left to change are the car's position and the camera's.
