Does anyone no how to obtain the Sage green color for fondant?

I used Americolor avocado sage green gel color for the border on this cake:

Wilton also has a moss green that works well.

I would use a medium green and add just a hint of brown.
Spring green + brown will make a yellower (avacaco-y) green
Forest green + brown will make a dustier green.

Thanks you guys, I went to mix colors today and had a brain freeze as to what would work.

i also use the avacodo color for one of my bridal shower cookies. its the perfect sage color.

Wilton has a pretty Willow Green that is nice.
