Welcome to FI...
I agree that the displaced threshold should be green not red.
I could not find specifically where it stated the appropriate colors of the threshold lights. But as reference, an FAA presentation stated that the approach threshold should be green and the roll out threshold should be red [www.faa.gov/.../airports/airport_safety/media/airport_safety_program_presentation.ppt].
In AIM 2-1-9e: "Pilots should never cross a red illuminated stop bar, even if an ATC clearance has bee given to proceed onto or across the runway."
Two schools of thought; 1. If the FAA has approved the simulator, keep the program going. 2. In reduced visibility scenarios, pilots could confuse the red threshold as a stop bar.
I know your question is regarding taking off, but since the FAA commented on circling, another thought is that no matter how you line up for a runway you will always see a green threshold unless you are flying past the departure end threshold.
Best of luck for a proper response!
