A huge aspect that I wanted to get right, was making the two worlds (and sets) be complete opposites and yet also completely the same.

Supplies, ready to go. 

           

Making all the set walls.  Without paint, the two sets were identical.  I needed to make sure I could leave the camera in place, swap the sets, and then keep shooting during the match cuts.

It fits!

          Getting the colors right.
