In the context of Asnières (Van Gogh series), explain the Parks of the Paintings.

Van Gogh's work in his first year in Paris retained much of the somber attitude and colors of his paintings from the Netherlands.  During the spring of 1887 he stayed with Émile Bernard at Bernard's parents home in Asnières.  During that time van Gogh began to incorporate the influences he had been exposed to over the past year.  His work lightened in "sun-drenched studies".  Landscapes began to dominate his subject matter, painted in "the glory of summer and the rich colors of the vegetation".  He now caught the sunlight between the leaves.
