Philippe Mahler primarily uses oil and watercolor paints, drawing on his training as an art glassmaker and stained-glass artist, as well as intensive study under Albert Chavaz. His painting technique is classical and based on nuanced color palettes, in which he recalls motifs and reinterprets them in new constellations. With themes such as water, earth, and the window as a symbol, he reflects the fragile balance between idyll and threat, making profound melancholy and the beauty of fleeting moments palpable.
