This painting is called “Père Tanguy”. It's a portrait of Mr.Tanguy. From the composition of the painting, we can see that van-Gogh put the main character in the center of the painting. Then he put many Japenese element surrounding the center character, such as the Mt.Fuji, the cherry blossoms, and the Ukiyoe. These are the symbols of the popularity of Japenese culture in Europe. So we can see that this is a Japonisme painting. And van-Gogh used complementary color, such as blue and orange, to make the painting clear. The artist also used vibrant color, and this also showed that Post-Impressionism also focused on color.
