Notice anything new on your last viewing of Avatar?

Have you noticed anything on your last viewing of Avatar which you didn't notice before on your last?

I have.

During several of my repeat viewings, I've always tried to learn how the movie fascinates me, or how the movie is made. During my last viewing of Avatar, I payed close attention to several scenes in the movie which went from bright to dark colors, or vice-versa. These scenes, which I believe immerse you into the film, stand out to me. Here are some samples:

1. The first time this transition happens, it is very subtle. The quick bright-to-dark scene occurs right after we see Trudy fly in the sunset in an attempt to find Jake's avatar. During this scene, we are presented with bright yellow and orange colors, where shortly after we are taken to the next scene, which is a quick transition from bright yellow colors to dark blue colors.
2. The second time this transition from bright to dark colors happens, it is right after Jake falls asleep on the hammock inside Hometree. We get a close-up of Jake's avatar's dark blue face, where we are then taken to the next scene, where the screen goes bright as Grace flashes a light into Jake's eyes.
3. The last and most notable scene which shows a quick transition between bright and dark colors is Jake's jump onto Toruk's back. Very simple transition, yet very powerful and immersing. I cannot help but think "Woah..." every time.

I probably missed some of the quick transitions, so if you noticed any which I didn't mention, please share.
