Pierre Bonnard
Pierre Bonnard was a French artist. He is well known for his use of colour, and in modern art, became regarded as one of the best colourists.

He was a painter, illustrator and printmaker and was a founding member of the Nabis, which was a group of post-impressionist avant-garde painters. He also became a leader of the Intimists.
His work was important because it was the transition between Impressionism and modernism. In his work, I can clearly see how much he was influenced by Paul Gauguin’s artwork and japonism due to the flat, yet bright colours, decoration, and stylized brush strokes.

Although the subjects for his paintings were rather simple, for example landscapes or portraits, he managed to capture such beauty with the flat depth and colour he used. I absolutely adore his choice of colour and how his style complements the compositions.
