At the recent Wayne Plein Air Competition, My painting "Afternoon at Androssan Farm" won the "Best Barns, Bridges & Backroad Award". This painting has many different greys. The interplay among the light source, reflected, and material local colors formed a subtle and rich color composition, which I really worked on recently on my landscape paintings. What should I do to make a shadow look like a shadow? What is the difference between grey and mud? How to make color play on a landscape painting more interesting? Those are a few questions I constantly ask myself.
