Here's some of my collection of color references. These are just grabs I got from the internet; nothing special.
However, would you mind recoloring that frame to match this one: http://i1238.photobucket.com/albums/ff493/ww123-2008/Camera%20Awesome%20Photos/iPod%20touch%20uploads/Song%20of%20the%20South%20Color%20References/null_zpsd71c3fed.jpg
The only reason I ask is because that frame still seems really dark (although that could be because we haven't brightened it yet), but I wonder if they used different color timing for each of the sequences (ie: a brighter approach for the first segment, a darker for the third segment, and a more natural for the second segment).
