The winter weather is gorgeous right now. The sky is a deep azure, with not a cloud on it - already some stars are showing - and there's not a stirring of the air. The colour of the sky is partly reflected off the snow on the landscape and the ice on the sea, which gives off the appearance of bleu celeste. Only streetlights, with their orange hue, offer contrast of colour, strung out like small gems along the roads - no house with light in it can be observed from our windows. This is certainly the blue hour.
