Just a paint job. Aforementioned Clinical-12 are blue, not green, simply
because they were sold to the medical industry. There are no other
differences. What is the orange one called?

Slang for a really big -12. Generally these were the expanded PDP-12s
with the floating point unit and hard disk (RK05, I think - there is
actually a "processorless" PDP-8/E chassis embedded in the expansion
racks, just to handle the RK8E controller).
