Tiffany Blue is one of the most famous brand colors in the world, a light robin's-egg blue used on the jeweler's boxes, bags and catalogs. Tiffany & Co. holds a trademark on the color in the US, and Pantone made a custom shade for it (Pantone 1837, named after the year the company was founded). The hex value #81D8D0 is the widely used screen version. The blue box with a white ribbon is an icon of gift giving.
