/ic/ - Artwork/Critique

In an anime studio, I heard that in betweeners require less skill than keyframers, so im assuming that rookie is more likey to get the job of doing a douga. But, are the people who do the final clean up = coloring more skilled for less skilled than the douga or genga people? In one hand, its the final product so it requires meticulous detail, but on the other, all they are doing is just coloring over sketches. I also feel that the genga artist would have trouble placing the shading and highlight maps without any experience in rendering beforehand. I just want to know which position a rookie animator would most likely get first.

tldr: rank douga, genga, and coloring artists in terms of skill.
