The Mets colors were almost pink and black because of a stable's racing silks
The New York Mets team colors were almost pink and black in honor of original owner Joan Whitney Payson's family stables, who wore silks of those colors.

The Greentree Stable silks were designed by Payson's mother, who modeled the pink and black colorway after one of her favorite dresses, according to graphic designer Todd Radom, based on an old account of proposed uniforms in a 1961 issue of the Sporting News.
The team eventually settled on a slightly more reserved blue and orange color scheme, but maybe someday the Mets will throw together an alternate-reality pink and black jersey, so the world can see what might have been.
