Tiffany Blue is the name for the light medium robin egg blue color associated with Tiffany & Co,, the New York City jewelry company. The color was used on the cover of Tiffany's Blue Book, first published in 1845. Since then Tiffany & Co. has used the colour extensively on promotional materials, including boxes and bags.
The Tiffany Blue color is protected as a colour trademark by Tiffany & Co.
The color is produced as a private custom color by Pantone, with PMS number 1837, the number deriving from the year of Tiffany's foundation. As a trademarked colour, it is not publicly available and is not printed in the Pantone Matching System swatch books.
The colour is so fresh, just like the ocean.
