I’d bet on it being closer to the render when itcs on track, the photo looks really poorly lit so the camera may not be getting all that great color accuracy

Although it looks a bit too dark for my taste, the live stream version looks better imo. I think the red will look red on-track too since thats the color audi racing uses

Red in the live stream orange in the render

The Audi Sport logo is red, so the livery will also be red
