Colour problem

[Piglet]

I got Casino Royale on blu ray today and watched it. It looks amazing, there's one problem though and I'm hoping it can be fixed. The picture is very off colour, sort of yellowy/orange, especially on the skin tones, the complexions on the faces look off if you know what I mean. Why is it like this and anyone else having problems? My PS3 is connected to my HDTV via HDMI. Could it be the HDMI? Or is it the blu ray? When selecting HDMI video output (or something like that) on the PS3, there's three options, automatic, RGB and another. The only one that works for me is the RGB one. In the other two the picture is bright pink and green. Any ideas??? Would really appreciate it. Hope I can sort this out.
