Process
I took a similar approach to that which I used for creating "The Fracture," but had to deal with the constraints of the car and the game engine in which the car would be rendered and playable.
Using Clyfford Still's "1957-D No. 1" as my inspiration, I attempted to create an original racing livery for the McLaren-Mercedes SLR 722. Still's "1957-D No. 1" fit quite well as the inspiration, since the color choice in "1957-D No. 1" is quite similar to that of the Pittsburgh Steelers. Originally, I tried to create a scratch-made livery for the car, which worked to an extent, but didn't physically fit in a way that I liked. I made some minor changes, like moving the logo forwards a bit on the hood and adding some fragmentation to the white sections. While this looked good in the image editor, it didn't work in-game. In fact, the game crashed when trying to render the image onto the car. After struggling with the original attempt and getting unsatisfactory results, I switched to using the Hamann livery as the template and modifying colors from there. The gold stripe is a homage to the gold stripe that runs down the middle of Steelers helmets.
