One slight problem is that the pictures do not all represent the same frame. It would be easy to fix by capturing one frame and then applying the algorithm and making outputs based on it (this should be easy to do using ImageMagick, for example).
Yeah, but the only true difference is the clouds having moved a little and maybe Sol's position being slightly different so it's not hard to do (by the way, in case you wonder those images were made by applying a color filter in-game).
As I said the factors with the square-based algorithm could be wrong, I was messing with these ones to see how well it works, does anybody else want to give them a try? I didn't check yet but at least I got the impression that it wasn't anywhere as off (this was mostly noticeable with red):
R = 0.25
G = 0.60
B = 0.15
