“Paul Sérusier's story was exciting. From his summer vacation in Pont-Aven, in Brittany [Summer 1888], where he had briefly encountered Paul Gauguin, he had brought back a small landscape painted under Gauguin's direction. Gauguin had asked him, (as Sérusier told his Nabis friends October 1888 in Paris): 'How do you see these trees? They are yellow. Well then, put down yellow. And that shadow is rather blue? So render it with pure-ultramarine. Those red leaves? Use vermilion.'”
