Fun fact, some of the more impressive examples from that era (like Mary Poppins) primarily used the sodium vapor process to get perfect mattes directly in-camera, no rotoscoping needed. It's a fascinating and impressive bit of tech: https://www.historicmysteries.com/science/disney-prism/39484/
That is indeed a fun fact! I am somewhat obsessed with sodium vapor lights and the bandwidth of light they produce. I would love to have seen the original camera rig and their special prisms, but apparently they only made three and they've been lost.
High intensity discharge lamps are awesome, can confirm. I miss when streetlamps were still HPS/LPS and mercury vapor, the lighting felt a lot more comforting than the harsh LEDs used nowadays.
