The quality of sunlight up there will of course be different from at sea level, far more harsh. I've only ever used slide film up high, and have never felt the need to remove an overall blue cast. Then again, getting colours of gore-tex and rocks dead on has never been all that improtant. Snow comes in all sorts of colours, flesh tones tend to be badly sunburnt anyway... The sky of course is a differnt matter. How near to black it is seems to depend on how much moisture there is around - a blue-sky morning that will develop afternoon thunderclouds is far less intense than the sort that will stay clear all day. And of course adding a polariser will generally take you well beyond mere solid black. I've had mist come out an awful pink on Velvia, although I'm not sure that it wasn't an abused batch of film (heat or x-rays or something.) Sensia mist is generally white.
