YeS i KnOw ThE wAtErFaLlS aRe PuRpLe! It's because in the game the palettes are always changing. I don't know why they're purple here. This is a Parallax Engine Thing I made.
I got these sprites off The Spriter's Resource. This is basically the alternate version of my Green Hill Zone tests. Instead of relying on clones and other faulty things, this one just has the sprites go back to x-0 y-0 whenever the position looks the same. It makes more sense if you take off the black border.
