Quick rundown of the 'greens' part: There are two blues and two yellows on the palette I was taught to use: Cerulean blue is a greenish blue, ultramarine is a purplish blue, cadmium yellow light is a pure, bright yellow, and Roman (or golden ocher) is a dirty yellow. With these four colors you can get four different greens: For a light, spring green (grass, or light coming through leaves as in the painting shown) I use cerulean and cadmium yellow. This is the bright, acidic green. Adding white or a touch of red or ocher is often useful to knock the chroma down. For the dark greens in the shadows, I use ultramarine and cadmium yellow. Even though the ocher looks darker, the chalkiness of it will make a lighter green. Cadmium yellow gets a rich dark shadow green. I'll add cadmium red medium to darken it even more. My favorite foreground or middle-ground 'tree' green is cerulean and ocher. It gets the perfect color of cypress or oak trees in sunlight. More ocher if it's late afternoon or sunset. The last possible green is ocher and ultramarine, it gives a grey, chalky green which I almost never use for foreground or middle-ground greens. I'll sometimes use it as a base color for olive trees. On the other hand it is very useful for distant tree-covered mountains. The brand of paint is very important for getting the right colors. For cerulean blue, Old Holland makes the best one but it is outrageously expensive. For less important projects, Williamsburg or most other brands are just as good. Ultramarine Blue Deep by Old Holland is the only functional ultramarine I've found. It's better than hand-ground ultramarines and is probably the one absolutely essential color on my palette. In my opinion, Williamsburg makes the best cadmium colors and their cadmium yellow light is perfect. Lately I've been using both their cadmium yellow light and cadmium yellow to vary my bright greens a bit. Zecchi's Roman Ocher is the best yellow ocher I've used, though Old Holland's golden ocher is a similar hue (if a bit stiff to work with, and slightly cooler).
