Prompt: Write a caption to appear next to Vincent van Gogh's "Portrait of Dr. Gachet" in a museum. In the caption, explain the mood the artwork creates and the tools the artist uses.

There are two versions of the painting. The first version of the painting was made in brighter oil colors. Dr. Gachet seemed to be enthralled with Van Gogh. The caption would be " Doctor Gachet's first impression."

The second version is darker compared to the first one. Doctor Gachet was painted with a grimace and sad expression. This painting was also made in oil on canvas. Both paintings had Dr. Gachet leaning on the table, but the colors differ, making the first one brighter and more jovial while the second one is melancholic and sad.
