In the garden, visitors encountered a freestanding pavilion coated with, and named for, the three primary colors, Blue, Red and Yellow. Visitors who entered the pavilion found it filled with artificial fog, a substance that interests Janssens as a way of giving sculptural form to light: “Gazing at mist is an experience with contrasting effects.  It appears to abolish all obstacles, materiality, the resistances specific to a given context, and at the same time, it seems to impart a materiality and tactility to light.”  As visitors moved through the pavilion, they experienced the profound disorientation prompted by losing all points of navigational reference; as light passed through the walls and ceilings, the fog became radiantly suffused with their colors, changing with the movement of the viewer and shifting with the light of the sky.
