Why is my iPhone 5 screen pink?

I charge it overnight, plugged in, face up, on the corner of the bed. Nothing happens to it, I just woke up and it was like this. Last time this happened (which was once), I noticed I had a phone update, so I updated it. When it turned back on, it was fine. But this time, there's no update.
Does anyone know what I can do? Why is my iPhone 5 screen pink

It probably got overheated. I would recommend taking it into an electronics store and see what they can do about it.
