Celeste arose from the blue adorning the arms and badges relating to the Royal Air Force after World War I. This influenced not only the name, but the bespoke paint covering almost every surface of the body. This name was officially etched into details of the car, while on the car's nose sits a GMA badge in 18K gold, a special request granted by Gordon himself solely for Celeste.

An ethos we try to bring to every car we touch is unifying and streamlining the body lines, and we have done this by creating an A-pillar mask that runs to the rear quarter, splitting to tinted carbon to blend into the glass of the roof. Within this split is the custom roof scoop mask with untinted gloss carbon, which is found on the rest of the exterior while also being the only T.50 to use it.

The standard wheel colour options were not sufficient for Celeste, so a bespoke light gold rim was created and tied into various other elements including a one-off gloss fuel cap with champagne Speedhead, light gold tinted exhaust pipes and even the button on the end of the handbrake.

One of the bespoke main themes of Celeste is hand polished aluminium. Door handles, centre console, tachometer inner bezel, gear knob, rear mesh grill, and even the speaker casing were polished by hand only for Celeste. This completely elevates the interior especially when combined with the entire carbon tub being gloss carbon fiber, another option unique to Celeste. If that wasn't enough, the steering wheel, seat and centre console support are all untinted carbon to show off the weave. Safari and Savannah leather swathe over the interior with black Alcantara dash for practicality.
