I can't answer the above questions for certain, but the Bauer customizer does have a new green this year, called Victory Green. The PDF makes it ever-so-slightly better than Kelly Green, I don't see it on the customizer. All the other new colors seem to be present (Coyote Red, Desert Sand, Ducks Purple, Retro Tan).
However, the first lines here - https://www.texasstars.com/news/detail/texas-stars-unveil-new-logos-and-colors says that the Stars do use Victory Green. So it sounds like that's what you're looking for?
