In 1837, Charles Lewis Tiffany and John B. Young opened the shop Tiffany & Young for stationery and other high-end goods in Lower Manhattan, just across from City Hall Park. Before the brand even became a major purveyor of silver—or solidified its name—Tiffany & Young began publishing the now-iconic Blue Book. First issued in 1845, the “Catalogue of Useful and Fancy Articles” featured a blue cover that skewed more green than the robin’s egg hue we now associate with the brand. Over the subsequent century, Blue Books varied in shade until around 1966, when the company settled on a color close to Tiffany Blue.
According to Andrea Davey, the senior vice president of global marketing at Tiffany’s, it’s difficult to pinpoint when turquoise became associated with the company, and it’s unclear why, exactly, the founders settled on that particular shade. Yet she noted that as early as 1889, the company used the hue in its display at the World’s Fair in Paris. “The presence of the color at the fair could suggest that by the turn of the 19th century, this shade of blue was already associated with Tiffany & Co.,” she said.
