T2 went from it's entirely red track/purple train scheme to black track retaining the purple trains.
Chang went from an entirely bright yellow scheme, to neon green track with purple supports.
According to word of mouth at the park... the park had intended to re-theme T2 as Batman: the Ride and Chang as Joker's Jinx. However rumor hat it that Gary Story (Six Flags CEO at the time) paid a visit to the park and single handedly nixed that idea. Chang's paint job had been completed upon his visit, but T2's was still underway. That is the supposed reason why not all of T2 was completed and that the station and station track remains red. I cannot verify this, but it does seem to make sense.
In the years since, the Batman Thrill Spectacular was canned, and the theming on Penguins Blizzard River has not been kept up. So I doubt the coasters will ever make the change.
Chang has been notoriously known for it's badly peeling paint. Literally within one year of having it re-painted, the coaster was flaking and peeling. This is probably a result of an improperly (or non) primed track. My perception is that rather than sand-blasting and priming, perhaps the painting contractors simply painted over the last paint job. Probably due to a request by the park to get the job done at a minimal cost.
