How about an open question. What color, by law, cannot be used in a lighted railroad signal?
WHITE
I’ll say taupe.
I’ll guess blue.
White?
It’d have to be white.
If another colored lens broke out, it’d display white. If white was legal to display, that could cause trouble.

White sounds like a pretty good option.
Puce? blue? Turquoise? Mauve? Black? Violet?
I’ll stick with white, final answer.

Not white–both PRR and B&O had (and still have) instances of white lights (clear lenses) in their signals (PRR’s dwarf signals use clear lenses).
Lunar white is also used on many western railroads and the B&O’s color-position-light signals.
Blue may not be used in a block or interlocking signal, but may be used to indicate a dummy mast.
Purple is used by some railroads to indicate a derail.
Anyone? Anyone? Beuhler?
Perhaps it is orange. It might be difficult to distingui***hat from yellow or red.
BLUE??? PINK???
Orange
Black.

Black
How can a lighted signal display black?
Duh! You’ve never heard of a black light?[;)]
I go with black also as it then appear to be a defective signal requiring the train to stop[:p]

I’m going to have to go with orange on this one.
Brown, because it can be misinterpreted as either yellow or red. Either that, or psychedelic.
…I do not know…!
White, is the answer.
How is that. Railroads do use white…
