Ultramarine blue to blue/teal and green horizontal diagonal and vertical brush strokes widely dispersed on a Cadmium to naples yellow background. Cadmium reds and burnt sienna in vertical strokes for the beard and moustache with horizontal browns flashed across the face and blending into the cheek whiskers on the artist.  The straw hat and coat he wears nearly blend with the similarly colored background with the border of the coat being hard to distinguish in places.  Vincent is experimenting with varying shades of one color and its complimentaries and perhaps foreshadowing the love of cadmium yellow forthcoming in Arles.   Painting, Oil on Canvas Paris: Summer, 1887 Van Gogh Museum Amsterdam, The Netherlands, Europe F: 469, JH: 1310
