Hello everyone. Quick question about rainbows---I have searched but not found a definite answer---

If you see rainbow ghosting on one movie, would it be the same for most others? I saw rainbow ghosts following Hancock in the bluray unrated version. It's when he's apologizing to the girl in his trailer. I have yet to see anything like this on other Blu's like wanted, Hulk,Walle , or a few others. Could it be movie specific? IMHO, Hancock has a lot of red push-even at natural settings. I'm thinking this could cause it. Or am I just being hopeful?
