I've never seen original :) and it was just an example. I'd say that colours in my "corrected" picture are not "untrue", but they are unreal. You are absolutely right. Colours can be corrected to.
Almost all digital cameras make mistakes in colours, and all of them have additional programs to correct it. My Olympus is always wrong about red, Canon is better, but not in all cases. There is a separate thread about cameras, so I think that it's an off-topic here.
