tricky greens

Recently when my teenage class was outdoors painting the common cry was, "There are too many greens!" Or, "Greens are boring, what do I do?"  Greens are incredibly tricky. In order to make a painting full of warm and cool greens to work you have to search for the other secondary colors that will complement green. That brings us to violet and orange. The famous Richard McKinley says, "The secret to green is orange and violet is its friend." So when looking at those endless greens out there now, think...where can I  see violet? How can pieces of orange in my greens and around enhance the green?
