I entered the latest daily paintworks challenge:
Paint this image using only burnt sienna, ultramarine blue and titanium white. That's it. No other colors. With that combo you can have it look pretty darn close to a full color painting by achieving a wide array of values and temperatures.
With the paint I had left over I painted this horse.
6x6 oil on canvas affixed to masonite board. $50 Buy this painting
