The color swatches in the photo here were mixed from the project's colors -- lemon yellow (PY 3), phthalo blue (PB 16), burnt sienna (PBr 7) -- plus a little titanium white (PW 6). It clearly shows how restricting your palette to only a few colors doesn't mean your color options are severely limited.
In the photo there's an over-representation of greens from mixed lemon yellow and phthalo blue, and an under-representation of yellow-browns from mixed burnt sienna and lemon yellow. Why? Simply I had more blue than yellow when I was playing with the colors in my sketchbook.
PY 3, PB 16, and PBr 7 are all transparent pigments, so work well for both mixing and glazing. Add white, and the colors shift to opaque. So the set of four colors gives you a whole range of colors to paint with.
