Oh, c'mon, that's from one dream sequence which exaggerates the dreary hospital lighting, I don't really think it represents the overall lighting of The Descent. In fact, most of the color saturation was red, given the cave flares.

What I like even less than florescent greens is that saturated blue lighting that's used to simulate night time. I don't want to pick on Guillermo Del Toro, but he's a director that comes to mind when I think of overly blue palettes:


And I recall Matrix Revolutions having some really ugly blue lighting. Give me the green of the first one any day over those endless blue shots of CGI machines fighting CGI machines.

It was a wm lopez comment--it wasn't supposed to make sense.
