Kolor is a subtle tribute to George Eastman (who liked words with the letter K because he thought people remembered them better) and his photography empire, Kodak. To select the color photographs for this vast project that have never been published in a book before, Elliott Erwitt sifted through his nearly forgotten ample archive of nearly half a million 35mm—primarily Kodachrome—film slides. Then he began the mammoth task of whittling it down to this epic collection of roughly 450 pages.
