Thanks for pointing out those colored markings. I believe I was mainly using a reference shot from the first season, which did not have the markings. Because I want to depict the sets with all their third season details, I will make the changes soon. I also added a red border around the plant-on with the yellow back-board. Thanks to your reference materials you posted on TOSgraphics, I was able to spot that third-season detail as well. You've been immensely helpful for this entire project thus far, and I thank you!
Oh, the Jefferies tube will come sooner or later. Just haven't gotten around to it yet!
I remember hearing that somewhere as well. But doesn't Styrofoam tend to degrade and break down when spray-painted?
