It only looks pink because of so much light reflecting off it.
Incase you didnt notice everything else is several shades lighter than it should be. Look in the last picture and the peoples uniforms in the background, its pink. Not sure what country this is in, but I doubt the cleanup crew will be wearing pink outfits.
In the last picture you can see the true color of the vehicle, as no direct light is hitting it, the shadows are going left.
