Unless the print was tinted or toned (unlikely in the 1950s) the print should not have any color to it except the “color” or the projection lamp — arc, xenon, or incandescent — but the eye adjusts to that quickly. Sometimes labs print B&W films on color positive stock (it’s cheaper) but there is a special ring of hell reserved for those labs.
It’s contrast/gamma and blacks that you have to get right. Remember, B&W printers had a scale of just 21 printing lights — and the labs usually processed prints to the same gamma (which might vary at different labs, but not by much).
Unless there are effects like day-for-night, or an attempt at an extremely contrasty look (that is, intentionally, rather than because of bad lab work or too many generations of duping), films of that era usually would have a good tonal scale, with no crushed blacks or blown-out whites. No color at all.
If you want to accurately mirror the look of a good vintage print, you probably should avoid windows and tricks — but of course sometimes it’s hard to avoid.
Good luck. Great B&W is amazing.

> But the question was how to know how the bw colors looked like on film when is released. We are working on a restoration project for a film from 1956. We projected 4 copies, all looked different. One was slightly yellow, other was grey without contrast, one was really contrasty and one is slightly gray with elevated blacks. The dvd copy is made in 1990s from the festival copy and probably has some grading on it too. How can we judge from this materials how this film supposed to look ?
