Two towers is full of that early 2000s push everything to blue or green style of digital color grading, and im not surprised that 20 years later they’ve decided not to recreate it. These regraded shots are arguably much better.

A shot like this is interesting

A lot of blue missing there

Other shots seem to keep the tone of the shot intact whist removing the blanket tint.

ROTK has a lot less big color washes. I havent had the chance to sit down and watch, im interested to see what their day to night grade looks in that scene where merry find pippin under the oiliphant. Looked terrible on Bluray. Also the horrendous shot of the gang meeting the pirate ships.
