 Van Gogh Museum 's Olive Trees : Bright Blue Sky ( F709 ) of cool , blue daylight tones is similar to Göteborgs Museum of Art 's Olive Grove , a study in warm autumn colors . The autumn toned painting met Van Gogh 's goal of achieving a " harsh and coarse " realism to his work . He presented the painting to his friend and doctor , Dr. Gachet , with whom he would be under care and supervision in Auvers @-@ sur @-@ Oise the following year .
