"Sunrise·Impression" is the pioneering work of Impressionism painting, which marks the emergence of Impressionism painting. It quickly became a worldwide painting school with far-reaching influence. It emphasizes the light and color of nature and takes the changes of light and color as the mainstream of painting. Monet is considered the first Impressionist master to use plein air techniques for painting. "Sunrise·Impression" depicts the scene of the port at sunrise shrouded in morning fog. Among the tones composed of lavender, reddish, blue-gray and orange, a vibrant red sun slowly emerged, dragging a wisp of orange-yellow waves in the sea water. The sea water, sky and scenery are intertwined and integrated in the relaxed style of writing. The three small boats in the offshore gradually became blurred in the mist, and the buildings, ports, cranes, ships, masts, etc. in the distance were also dimly visible in the morning light... All of this was seen by the artist from a window. Painted. Such bold use of "scattered" brushstrokes to show the scene of mist blending. This is an artistic rebellion for the artists of the Salon School, who have always been orthodox. This painting is completely driven by a momentary visual experience and a lively and vivid painting mood. The cautious and clear outlines and dull and rigid tones that were respected by official academic art in the past have disappeared. This rebellious painting aroused official opposition.

This famous painting is a sketch painted by Monet in the port of Havre in 1872. He also painted "Sunset" at the same location. When it was sent to the first Impressionist exhibition, neither painting had a title. A journalist ridiculed Monet's paintings as "a denial of beauty and reality, which can only give people an impression." Monet then gave this painting a title - "Sunrise Impression". As a seascape sketch, the entire picture is shrouded in thin gray tones, and the brushstrokes are very random and messy, showing a scene of mist blending. At sunrise, the sea is foggy, and the water reflects the colors of the sky and the sun. The scenery on the shore is vague and blurry, giving people a momentary feeling.

When Monet and a group of young painters held an exhibition in 1884, this "Sunrise Impression" was slandered and ridiculed. Some critics said sarcastically: "The rough wallpaper is more complete than this seascape!" Some even used the title of this painting to refer to the young artists led by Monet as "Impressionists", so "Impressionism" became won the laurels of this painting school.
