Major members of the Düsseldorf School advocated "plein air painting", and tended to use a palette with relatively subdued and even colors.
The Düsseldorf School derived from and was a part of the German Romantic movement.
Prominent members of the Düsselorf School included von Schadow, Karl Friedrich Lessing, Johann Wilhelm Schirmer, Andreas Achenbach, Hans Fredrik Gude, Adolph Tidemand, Oswald Achenbach, and Adolf Schrödter.
