What artistic features distinguish Paul Klee’s Tunisia watercolours?

Paul Klee’s 1914 trip to Tunisia was a pivotal moment in his career, marking his transition into a confident colorist. His watercolours from this period are distinguished by the following features:

• Simplification of Form: Klee simplified the North African landscape into transparent, coloured planes.1
• Sustained Use of Colour: These works represent his first significant body of work created in colour, moving away from the black-and-white focus that had previously dominated his output.1
• Lyrical Style: The paintings are characterized by a lyrical quality that served as a stylistic and thematic foundation for much of his subsequent painting.1

This newfound assurance was influenced by his intense response to the landscape and the work of his companion, August Macke, whose approach incorporated the colourful Cubism of Robert Delaunay.1
