This project was concieved by KA PAI studio, during the Covid pandemic, for the city of Brussels. KA PAI studio wanted to brighten the sky of the city during difficult times, and celebrate its diversity by embracing the joyful colours of the rainbow. The goal was to maximise the scale, lifespan and WOW of a floral installation whilst reducing its environmental impact.  Located inside the Galeries Royale Saint-Hurbert over the summer of 2021 the installation was designed for the fresh hydrangea's to dry in-situ. The project generated significant media interest.
