I had the Inktense 12 pencil set, so I did not have the beautiful iron green from the project example. I used  poppy red (and a little fuchsia with it in the field), deep indigo, sea blue, olive green, apple green, a little teal green, and baked earth. I would love to add a few more colors to my collection. These are really fascinating and I'm a little more comfortable with them now than I was! I hope to find ways to use them out and about. Thank you!
