Color Notes - Making Green

I recently was teaching a private student how to paint Olives for a still life.  She had no green suitable for the painting in her paintbox.  No Problem!  Another way to make greens is to mix Ivory Black with Yellows.  You can get some really natural greens this way.  So we used Ivory Black and some Cadmium Yellow Pale with a bit of white.  Go easy on the white!  I also have made wonderful olives using Yellow Ochre for my yellow in the mix.
