The view of the red sunset is somewhat beautiful, it's looks like a bloody evening. I have seen this a couple of times in real life and my experience was lovely. I really can't say what the cause of the red sunset is but at least we know something triggers the sunset to become red. If you've not had the experience, I'll advise you do.
