Carnovsky's RGB Wallpaper

From Creative Review

For the Milan Design Week, Italian studio Carnovsky
created a series of wallpapers that react to different coloured lights

UPDATE: new versions of the wallpapers are 
on display in a new exhibition in Berlin alongside 
prints and playing cards using the same technique. 
See our story here

The designs were created for the Milan shop of
Janelli & Volpi, a noted Italian wallpaper brand.
Each features overlapping illustrations, different
elements of which are revealed depending on
whether a blue, green or red light is shone upon them.
