The exhibition extends outdoor with 4 colours at 3 metres high (2011), a variation on the theme of pergola and «attrape soleil», which Buren has explored in several
public works, which play with outdoor light, the movement of the sun and coloured shadows such as La Tonnelle, presented at the Venice Biennale in 2007, or the covered
walkway Passages
under a colored sky (2007) in Anyang, South Korea.
