Consistent color throughout a film

[Andrew Brinkhaus]

After seeing Assault on Precinct 13 on FX the other day, I noticed that the last half of the film is lit around a blue color pallete, more particularly what looks like a single gel. My question is whether or not it might be a combination, or if the shot to shot color, which in the film looks identical throughout the last 20 or so scenes could be the result of a single "key" gel. See reference below for example.

Having not seen the film, I'll go out on a limb here:

It's both lighting control, as you get with any big budget film, as well as color correction later on. As you saw it on FX, it went through a telecine session to be put onto a video format for broadcasting. Therefore, any discrepancies between shots can be fixed very easily.

As for the gel, might be steel blue. Can't tell too well from the image on my monitor here.

Thanks for the reply Adrian. I understand the aspect of converting a film for TV, I really was just curious about the potential of these scenes being mainly lit with a single gel type.

Well they certainly would've had the budget/crew for it, so it's probable that the used the same gel/gel combination on the shots. The "exact matching," however, almost always comes in post AFAIK. You can get damned close on set, but there seems to always be one or two fine variable to skew it a bit.
