This skin is inspired by the doppler effect in light, in which a light source moving toward the observer would shift blue, and shifts to red when it's moving away from them, which means, in theory, that this special feature may create the impression that your car is more difficult to chase seen from the car behind (red shift), and that you're closing in quicker seen from the rear view mirror from the car ahead (blue shift).
This greenish reptilian skin was made in honor to the Green Hell (Nordschleife), whose laser scanned version is due to release by Kunos any time now.
I really like the idea, it's very original. You did a great job, the car looks good. As a physics enthusiast, it's good to see a physics concept applied to an artwork. Thanks!
