Agreed, though at times "Hero" is borderline heavy-handed with color. However it manages to remain beautiful. One thing I've learned, though, from a set-designer friend, is that nearly every movie is highly attuned to color and lighting.

If you're looking for other films that use color in interesting ways, check out the "Three Colors Trilogy" by Kieslowski.

Same here, I remember loving the vivid imagery of that movie.

I watched "The Fall" recently and this is the first one that came to mind. Highly recommended: http://www.imdb.com/title/tt0460791/
