Agate Grey Metallic on the 991 Targa: A Quiet Body and a Bright Bar
Historical color study: the source identifies a 2017 Targa 4 photographed May 12, 2022. Naming context comes from Porsche’s October 23, 2017 Carrera T announcement.

Agate Grey Metallic lets the Targa bar be the brightest large detail on this 911. The body carries a softer sheen, while the open cabin and dark trim create a separate band above it. The result depends as much on material contrast as on color contrast.
A name used for bodywork and accents
Porsche’s October 2017 Carrera T announcement names Agate Grey Metallic as the finish on that model’s Sport Design exterior mirrors. Here, the photographer identifies a different car: a 2017 Targa 4 with Agate Grey Metallic bodywork.
The two applications illustrate why the same color name can appear in different parts of a specification. A mirror finish on a Carrera T is not proof of the pictured Targa’s factory order; its color identification comes from the photograph’s documentation. No individual Paint to Sample status is claimed here.
Grey against silver
The bright bar makes a clear vertical division behind the seats. Silver wheel faces repeat its lighter tone lower down, while black intake slats and tires anchor the body. The grey paint sits between these extremes, allowing the curved rear quarter and raised front fenders to remain visible.
Reflections from buildings and sky create broad pale patches across the hood and door. Those patches are useful clues to surface shape, but they are not separate paint tones. A tightly cropped swatch from one of them would be a poor guide to the car’s overall appearance.
Use the full Agate Grey Metallic name when collecting references, and keep the photograph’s date attached. This is a study of how the documented color looks on a particular Targa in daylight; an exact repair or paint match still depends on the individual vehicle’s identification and a physical sample.
