Lebasque's vision was coloured by his contact with younger painters, especially Édouard Vuillard and Pierre Bonnard, founders of Les Nabis,[1] a group of Intimist painters that first favoured the calm and quietude of domestic subject matter. From his first acquaintance with Georges Seurat and Paul Signac, Lebasque learnt the significance of a colour theory which stressed the use of complementary colours in shading.
His time in South of France would lead to a radical transformation in Lebasque's paintings, changing his colour palette forever. Other travels included the Vendée, Normandy, and Brittany.
Lebasque had some commercial success during his lifetime. He worked on the decorations at the theatre of the Champs-Elysées and of the Transatlantique sealiner.
