Those old black and white television cameras had a lot of limitations. For instance, things that were white and glossy would cause an extra-bright flare effect that would leave trails across the screen whenever it moved, and it was even worse on video. Guitar companies had to invent a brand new shade of yellow for musicians who performed on TV that still looked white on camera, but didn’t light up like a road flare under the studio lights.
Which is a long way of saying that when it comes to those old cameras I would expect the light from a blowtorch to cause some weird artifacts.

Got a source on that guitar thing? That’s interesting.
Not off the top of my head, but the paint color is called “TV Yellow.”
As a related phenomenon the Addams Family set was painted in colour so that each element would show distinctly on black and white television.
