MY PERSONAL COLOR MIXING EXERCISE - ROUND EIGHT - sketching a little 9" x 11" oil portrait once a week with a different triad of colors. This handsome young man, Malcolm, let me snap his picture.  He is painted with VENETIAN RED, YELLOW OCHRE and SAP GREEN along with WHITE and a little BLACK. The raw paint became the abstract on the right.  
For me, the purpose of this little exercise is to show how flesh tones can be created out of any number of limited palettes. Artist friends have been suggesting some of the "classic" palettes and I'll be posting some samples of those too. Thanks for all your feedback!
