Occult orchids

Pop-up flower shop Fleurs des Rêves, or Flower Dreams, sold flowers dipped in thermodynamic ink, causing them to change colour in response to different thermal stimuli.

Perrier-Jouët created its bouquets with the help of experience designers Bompass & Parr. The duo treated the plants with a liquid crystal dye that is transformed from a deep satin black to champagne bottle green, and coated the blossom in a black thermochromatic dye that reveals the original pigment under heat.

Fleurs de Rêves also hosted workshops where guests were shown how to coat the flowers in thermodynamic ink to create their own colour-changing blooms.
