What color is the iconic Tiffany Blue box?

The iconic Tiffany Blue box is robin’s egg blue. The color is a light, medium blue-green shade associated with the American robin’s eggs and is commonly described as robin egg blue or robin’s-egg blue.

Tiffany & Co. used the color on the cover of its Blue Book catalog, first published in 1845. Over time, the shade became central to the company’s packaging, shopping bags, advertising, and broader visual identity. It is now so closely linked with the brand that people often call the hue simply Tiffany Blue.

The color is not merely an ordinary commercial paint choice. Tiffany registered Tiffany Blue as a color trademark in 1998, and Pantone produces it as a private custom color identified as PMS 1837—the number referring to the company’s founding year.

Sky blue and baby blue are looser descriptions that can cover many shades. Teal is generally darker and greener. The canonical answer points to the specific robin’s-egg color association, rather than any generic pale blue.
