Umm, I might be doing something wrong, but all the RAW's that I am shooting, turn a very strong Purple/Pink colour.
The whole scene is this major Purple/Pink colour.

Shot in sRGB, using photomatix to view the RAW's. Canon 500D camera.

Do I need to shoot in Adobe RGB?

EDIT: (it wasn't astro, but doing daylight tests with the new camera)
