Pantone 1837 represents Tiffany Blue, the signature color associated with Tiffany & Co.
The distinctive blue first became associated with Tiffany in the nineteenth century. Charles Lewis Tiffany selected the shade for the cover of the company’s 1845 Blue Book, the annual catalogue of its jewelry collections. The color was later used on Tiffany’s boxes, bags and other packaging.
Tiffany Blue resembles a medium turquoise or robin’s-egg blue. The company treats the shade as a protected trademark in connection with its products and packaging, so it is more specific than simply calling the color turquoise.
Pantone assigned the number 1837 in reference to 1837, the year Tiffany & Co. was founded in New York. The color is often confused with generic robin’s-egg blue, but Tiffany Blue is the brand-specific name connected to the company’s visual identity.
