The Matrix kind of did this, with the switch in color saturation & tint between "inside" the matrix and "outside." Inside was desaturated and tinted green; outside was desaturated and tinted blue. At the time it was considered a nuanced way of exaggerating the difference between the two.

The Wizard of Oz used this in the sense that they saved the change (from black and white to color) for a later point I the movie (about 7 minutes in, iirc). Rather than the movie starting in color the transition was used to ad splendor to the world of oz.

Sunshine did that, by depraving you of red and yellow for a while and then panning out of the ship to show you our sub in all its glory.
