Re: TOS Door Colors
Here is the screencap from "Charlie X" near the ship's galley (transporter room corridor set) with the turbo lift sign reading "turbo lift 3" which I mentioned earlier in the thread: http://tos.trekcore.com/hd/albums/1x...rliexhd187.jpg
Other than "2" and "7" I'm currently not aware of signs with different numbers, in the later two seasons we had less close-up shots of the turbo lift doors.
