In order to get the answer, first we need to get to know about the masterpiece and about the artist who made that masterpiece. It is not simply said to be a masterpiece as it is one of the epic forms of the art world.

Lots of facts and myths are revolving around this painting but truly it’s a magical exposure of Van Gogh’s vision of the night.

THE STARRY NIGHT, By the time Van Gogh painted The Starry Night, he had developed a personal style so unique that even a layman could easily recognize his unsigned paintings.

The night sky depicted by Van Gogh is the brightest illumination of shining stars and sky. Inspired by the view from his window at the Saint-Paul-de-Mausole asylum in Saint-Rémy, in southern France, where the artist spent twelve months in 1889–90 seeking salvation from his mental illnesses. 

The swirling composition of the sky and the gloomy blue color palette have caused the painting to become one of the most recognizable illustrations of all time. 

Looking into The Starry Night

The Starry Night by Van Gogh was painted with a loaded brush. The painting shows swirling swirls in the sky that give it fluidity and a sense of continuity. The vivid colors in the piece also suggest emotion rather than realism. It has been argued that it could have been caused by lead poisoning, causing him to choose odd colors. It seems likely he was representing the night sky in a way that was particular to him, as well as its rich colors. The image is constantly switching colors, jumping between Prussian blue, and cobalt, to ultramarine and Indian yellow of the moon, and the bright cadmium yellow surrounding the stars…

Although at first glance, the art piece seems to be hallucinating and the supernatural however keen observation reveals a deeper symbolism, in which the artist’s worldview is amalgamated into the masterpiece. Van Gogh conveys his emotions through the contoured forms, of his health condition and his quest for its advancement, and his battle against the condition is reflected in the opacity of the nighttime sky. The sky, the clouds, and the stars, all seem to be moving, giving a flow to the expression of the artist’s emotions.
Van Gogh dazzlingly uses several elements of design to create a magnificent description of a starry night from his imagination.

The lines are organic and have a wave pattern, which illustrates swirling wind, rolling hills, and the mystifying texture of the sky.
He has used short brush strokes, even with his style, to assemble spirals of clouds, swirling the wind and the cypress bush; this creates a deep sense of a rousing feeling and depth, constructing a strange atmosphere.
