David Brownlee and David DeLong, authors of Louis I. Kahn: In The Realm of Architecture, declare that "in Fort Worth, Kahn created a skylight system without peer in the history of architecture." Robert McCarter, author of Louis I. Kahn, says the entry gallery is "one of the most beautiful spaces ever built", with its "astonishing, ethereal, silver-colored light." Carter Wiseman, author of Louis I. Kahn: Beyond Time and Style, said that "the light in the Kimbell gallery assumed an almost ethereal quality, and has been the distinguishing factor in its fame ever since."
