It's also why celeste is infamously difficult to match (regardless of which era mix was used).
Neon green does have a problem standing out against a backdrop of green, like trees. There was once a picture on YouTube that showed a cyclist wearing neon green riding through a city, he stood out really well, but when he was riding through a thickly tree lined area he blended in and was more difficult to see. But when they changed to a neon orange the rider stood out better against a tree background, but not so good in a city background. They don't have a safety vest that combines the green with the orange, which makes me wonder why? Is there some sort of issue doing that that I'm unaware of?
