The first thing you learn in color theory is that ALL colors are made up of the basic three: Red, Yellow, Blue. Bear in mind that we are talking about mixing pigment here, not light.
So here is my quick study using only three colors and white.
Cadmium Red......Cadmium Yellow........Ultramarine Blue.......Titanium White

And, by golly, it works! With those three colors I was able to get a full range of palette colors.
Now, I won't be tossing out all my other beloved colors, but it does mean that I can be more confident about lightening the load when I take to field and forest in search of a good spot for plein air painting! The fewer colors I carry the lighter my pack. More to come.
