I'm confused where they've actually got the colour from, I assume its the main stripe colour on the shirt, and not some minor trim I'm not seeing?
The fact they call the shirt 'green' doesn't help - I've never seen anyone call the 99 shirt green in any way before.
A lazy effort all round from where I see it, and perhaps fitting for a shirt that will be worn probably 4 times.
It's not the main stripe colour. If you look very, very closely at the playoff final kit, the stripes are separated by very thin neon green bands. That's the colour they've copied, hence my bemusement at why they didn't copy a different part of the shirt.
