Does this mean that in semaphore days a distant placed below a home signal
displayed a red light when showing "caution"?  Certainly that is the case in
Victoria.

Interestingly, to the best of my knowledge,  in the UK such an arrangement
shows a yellow light at night from the distant, meaning that R/Y means STOP.
