Upon re-reading this quote and its source article, I believe he was probably referring to moviemaking at a more meta level; i.e., there's no decision-making process wherein all (or many) filmmakers discuss and agree upon a narrow choice of colors to use across all of their films. As the quote continues, "[e]very film has its own look."
I inferred "we" as meaning a single production team. It makes much more sense if "we" refers to filmmakers as a whole.
