22.9.2008 While a friend of mine was preparing a delicious Italian dinner, I wandered around in his apartment and ended up looking out of the window facing to the interior yard. The day had already turned into night so neighbours had switched their lights on. Lit rooms formed an interesting mosaic of light; some lights had warm colour while others were cooler, few were slightly green and some a bit reddish. I think I spotted a blue one too.
