Thanks Steven! I guess that my current mixture will be a good starting point for me. It does look a lot like the soft green that I am going for, but having experience with only a limited number of pigments I was interested to see if there were any popular mixtures out there.
Of course, the plus is that at the moment I am using pigments that I already have in my palette. Good for both the wallet and the unity of the painting.
A "Whitaker Green" futon cover, I hadn't expected that!
