Thanks Aldous. If you look at the sky in the picture, it's natural blue isn't it? I have mentioned it before, but somehow up north of the polar circle at night time which this is, the reflections from the sky is amazing, unbelievable but true as it's seeen. Just as remarkable to me as to you. Can't vouch for your monitor though. Remember that there is this light for 24 hours for more than two months. In the same area we also have at winter time the Aurora Borealis / Northern light.
