Tiffany’s first used their blue on the cover of their catalog in 1845, 20 years before Lincoln was President and over 40 years before our ClockTower was even built.
They own that blue now. No one else can lawfully use it for a retail image.
Pantone calls it #1837 although as a trademarked color, it is not available in their swatch books.
The concept of a Tiffany gifting box was introduced in 1853. This box held the grand prize at the Parisian 1878 World’s Fair.
This color has been a recognized symbol of luxury around the world since 1845.
Now you know.
