Steven,
Thank so much for providing an excellent and most thorough response to Jeff's inquiry. I agree with your description. I also think that, like many other very accomplished painters, Greene's eye is so well-trained, he just skips the part with the measuring. tool. Personally I need that tool. Like the carpenter's rule, I measure twice, put once. (Then I measure again.)
Geri,
Thanks. I used Daniel Greene's palette, which is as Steven describes
here Most of the colors (all the earth tones plus sap green) were foreign to me, but they work. Ultramarine blue is an optional color. All of Greene's oil videos describe the mixing process. It makes a lot of sense to pastellists because it follow the idea of one hue, with six values for each of several colors. Then the decision to make is: Is it warm, cool, or ochre?
