Haven't seen that, but another example is Dancer in the Dark, which contrasts not just with color. It has primary narrative sequences that are cinéma-vérité style with dull colors, spoken dialog, handheld cameras and no background music. Then it has musical sequences that gradually transition from that style into choreographed, boom-camera, saturated color. The transformations are very well done and the contrast is really effective.
