Over on Jets Reddit someone has claimed to see them, described the following. Obviously this is a random Reddit account but they way he describes the names of the colors reads like it's from a press release.
"It’s a bold “NY”. The whole set is way more representative of New York City than it is the Jets branding, and I actually really like that. The black set is even a love letter to the “City that never sleeps”. The new colors are “Big Apple Green”, “Jet Black”, and “LimeLight”. It’s definitely different, it’s striking, it’s not like anything in the NFL, and to me looks like a team tired of playing second fiddle ready to, well, embrace the limelight.
The numbers are probably my favorite part. Absolutely massive."
I asked him where did he get the names of the colors
"The press release. “Big Apple Green” is a deep shade of green that is rich but still appears to glow, “Jet Black” is exactly what it sounds like, and “Limelieght” is a bright neon green with an almost yellowish tinge to it."
Edit: I hope it's not true, sounds like there going heavy black and ignoring the white.
