CHICAGO BOARD OF TRADE BUILDING

CNL Projects worked with Gensler and R2 to curate and manage the commission of Golden Hour – Yellow Light to Dark, a dynamic ceiling mural installation by Luftwerk for the iconic Chicago Board of Trade building.

Yellow Light to Dark responds to the Chicago Board of Trade building’s iconic Art Deco style with the ceiling mural’s perspective gradient of yellow.  The color system for this mural follows the tradition of the Art Deco palette which referred to ancient Egypt for its color, specifically in its use of gold using orpiment. Orpiment is a rich deep yellow from the mineral auripigmentum (“aurum” meaning gold and “pigmentum" meaning pigment). Yellow Light to Dark uses Cadmium Yellow which is the modern replacement of orpiment.
