To my eye, Pantone 382 & Pantone 389 look almost the same, one is just a very subtle shade lighter than the either. If that's the color you like, I don't think you'd be unhappy with either one.
If I were to order the 29+ frame from Workswell, I was going to have them paint it Pantone 320C, a similar green to what Yeti uses on their frames. Since they said they could not do metallic colors, which would have been my first choice, a solid Pantone color was all they offered.
