This is a color assignment. The color palette node I mainly used in this assignment was Grade. I mainly wanted to give the impression that the light was hitting the tail of the plane. So I roto the tail, and I do an extra color palette on the tail.
This is not a difficult assignment. But color modulation is a very important part of the post, and it is a very important job to make different elements of the scene match each other.
