This is something photographers and filmmakers had to (and sometimes still have to) deal with when shooting on black-and-white film, surely? (Though maybe B&W film sometimes has noticeably different responses to light at different visible frequencies, which might happen to counter this, or to heighten it?) There’s a long history of using colour lens filters with B&W film.
Yeah, B/W film was definitely not all that accurate. It was a common practice to use weird makeup, lighting, colors, in order to create a B/W film image that looked correct (see chocolate used for blood).
So in those cases, filmmakers had to counteract the limitations of the b/w transformations in the actual sets.
