Films with awesome colour grading

A film i adore is Hero. Chinese martial arts film. I think it has some of the most extreme colourgrading changes int all cinema, but the amazing thing is, you dont actually realise when it changes. Its done so well:

The colors reflect emotions and really help tell the story. Like when there's flashbacks to the past with characters family's there is a warm yellow grading and like i said before, you just don't notice the transition.

Another film i recently watched is limitless. Brilliant film; the story is about a guy who takes a special drug which makes him have an enhanced mind. But the effect doesn't last so he needs more and more. Quite appropriately, when hes off the drugs the color grading is very de-saturated:

Hahaha







And then when hes on the drug, his whole world brightens up, saturation overload!!:

Really its not that saturated but because the de-saturated grading before is so intensely dull, it makes this look soooooo much more different
