I don't think the blue cast is cause by the morning lighting. I experience the same blue cast on my LC5 and some noise if you look at the metallic surface carefully. Hmm... wonder if anyone can help to solve this problem.
kueko... probably it is too smart. I read in one of the review that says that it is over intelligent by taking the initiative to auto-level and adjust certain colours should the most of the whole picture consist of one outstanding colour.
So for both our pictures turned out bluish probably is the reason for such occurrences ;P
