Maris became a master of the grey palette. He used thick layers of oil paint to capture the damp air of the Dutch coast. His compositions often feature low horizons. This allows the sky to occupy two-thirds of the canvas. In works such as Landscape with a Windmill, he focused on the light through clouds. He frequently reworked his canvases. He dragged dry brushes over wet paint to create a sense of movement in the water.

Modern collectors value Maris for his ability to evoke mood without relying on bright colours. His works offer a sense of quiet that suits contemporary interiors. The muted tones of his harbour scenes provide a neutral aesthetic. He avoided sentimental subjects. He preferred to document raw weather and light. His work remains relevant to those who appreciate technical skill and atmospheric realism.
