The first company in American history to successfully trademark a colour

In the late 1950s, Owens-Corning was facing steep competition from other fibreglass insulation companies.  Owens-Corning decided to distinguish itself by infusing its product with pink dye. The company adopted the slogan "think pink" and spent tens of millions of dollars advertising the colour.

In 1985, after a 5-year battle, Owens-Corning became the first company in American history to successfully trademark a colour. Ten years later, the Supreme Court ruled that colour could serve to identify a brand.
