The Mets' black home uniform, which returned during the 2021 season, was originally introduced in 1998 when the team unveiled it during an event where some of the players modeled the new duds.
Along with the black jerseys came a black hat with blue "NY" that was outlined in orange and white. And the Mets soon introduced a black cap with blue bill that had a blue "NY" outlined in orange.
The introduction of black as a Mets color also soon led the team to add black drop shadow to the home pinstripe jersey, home snow white jersey, and road gray jersey (on the "Mets" at home and "New York" on the road, and on the front and back numbers and name on the back), which -- to this writer -- was a step too far and came pretty close to ruining the above uniforms.
To be clear, the black jerseys are sharp -- as are the black hats (which also returned in 2021). But that the color black took over the rest of the uniforms in the rotation back in the 90s and into the 2000s -- and that the Mets pretty much stopped wearing the blue caps on the road at one point -- was a very, very bad development.
Ahead of the 2024 season, the Mets made a big change to the black unis, removing the white shadow from the logo on the hat and from the the "Mets" and numbers on the jersey.
With black back in the rotation, here's hoping the rest of the uniforms are left black-drop-shadow-free. Oh, and if they want to bring back the black road jerseys (more on those below), that would be cool.
