Huh, I checked out the screenshot gallery and you're definitely correct. For me, the inflatable centrifuges have tan bits on the joints kind of. I looked into the development threat, but I just have the version from the listed links, 1.4, not the 2.0.0 build. I've tried running the game with no other mods installed, besides the required ones, but no luck.
Edit: Here's a screenshot of the Coriolis centrifuge.
