In all, 40 different colours and 41 thousand pieces of aluminium make the building's cladding its most characteristic feature. Hues vary from earth tones to grey, light blue and green.
The building is completed by a sunshade system designed and positioned on the basis of the angle of the sun's rays.
Nouvel's intention was not simply to create a skyscraper unlike any other, but to make a kind of new spire suggesting movement in ascension, a great fluid mass that looks as if it has grown out of the earth.
