They won't stop. Warm-cool color combos (orange/yellow vs blue, teal vs orange, cyan vs red, steel vs red etc.) provide the most color contrast, so the picture always looks "bright" and "vivid" to a casual viewer.
BTW, the trick is far from new. Some examples that come to mind are Aliens and Terminator 2 (blue/gray vs red/orange, done via lighting) and Empire Strikes Back (again, blues vs reds/oranges -- very well nuanced across the entire movie except the Yoda swamp scenes).
