Without the branding of Tiffany & Co. the color might not be as popular as it is today. The company explains, "Tiffany Blue boxes and shopping bags epitomize the jeweler's great heritage of elegance, exclusivity, and flawless craftmanship."
Many associate this color strictly with Tiffany's, and when they see the color they immediately think of Tiffany & Co. The color is also assocaited with a calming feeling and have been used in clothes, furniture, and for many other accessories.
Although the only company that is allowed to use "Tiffany Blue" as a color is Tiffany's itself, because they have trademarked the actual blend of color. However, many companies can use similar colors just not in the form of a jewlery box.
