Three Colors: Blue (French: Trois Couleurs: Bleu) is a 1993 French film written, produced and directed by the acclaimed Polish director Krzysztof Kieślowski. Blue is the first in the Three Colors trilogy, themed on the French Revolutionary ideals; it is followed by White and Red.
I watched this film before going Paris trip. I focused on the blue colour and image of Paris (Paris is the background of the film). In the film, blue colour appeares in the various spaces and situations with urban atmosphere of Paris. It is interesting experience to link together with one colour and the image of a city.
When I visited Paris, I could enjoy the night view of Paris thanks to public bicycle rental programme Vélib'. It was cheap and easy system.
Vélib’ means free bicycle or bicycle freedom in English. The system was launched on 15 July 2007 by Paris mayor Bertrand Delanoë. Ten thousand bicycles were introduced to the city with 750 automated rental stations each with fifteen or more bikes/spaces. This number has since grown to 20,000 bicycles and 1,450 stations, roughly one station every 300 metres throughout the city centre, making Vélib’ the largest system of its kind in the world.
I believe Public bike rental system is truly good way to save energy and have environmental benefits as well as to offer easy transportation for tourism. A lot of other Europe Cities, Barcelona, Copenhagen, Luxembourg, etc. also have this system. In case of London, Mayor Boris Johnson, himself a keen cyclist, has plan to introduce a similar system in London in May 2010.
