I think you are going to want something other than Burlington Northern or CN green #12
just a week before the RPM announcement, I went hunting for a good PolyScale Willow Green,,,,,I brought the two above colors home and chipped them out,,,,,,,,,CN Green #12 is just a little lighter than 14115 and Burlington Northern is close enough to 14187 Willow Green that I am going to use if for my Acrylic Willow (no one makes Willow green in Acrylics)
for 34151 Interior Green, I have PolyScale 505308 RLM 67 Dark Olive Green,,,,,,,,I didn't get that far with RR 1 oz bottles, yet,,,,,,,,,but 414376 Reading Green looks pretty close to 34151
