Initially I thought I'd have to go predominantly with the goldenrod, but after checking my bin of greens I found I had quite a lot of the exact "spring green" I needed. Once I added in a chocolate brown I was able to ditch much of the goldenrod which I didn't really care for. I still have a touch of it though -- challenge rules require it.
Listening to the comments here and on Ravelry I'm going to add in an orange-red for zing.
