We tried about 6 different shade of BM green - so I've tested a lot! We were looking for a green that was a little brighter than sage, but I can tell you a few colors to check out.
Iced Mint - looked nice on the swatch, but came out much too flourecent for us.
Kittery Point Green - we ended up using this, but i think it would be too bright for what you are looking for.
Hollingsworth Green - This is dull/darker than the other.
Prescott Green - Has a little more blue in it than the others
Guilford Green - Has a little more yellow in it than the others
Spring Valley Green - This is inbetween the prescott and guilford.
I can't remember exactly what the colors were, but I used two shades of sage green (one dark and one lighter) and pale pink. I also used a hot pink too and I really like how it turned out. Here's a picture that shows the stripes really well.
