A curation by Flavio Scaloni, Gallery Manager at Galerie Lo Scalo - Blue in the city serves as a chromatic lens for exploring the duality of urban existence, symbolizing both the infinite sky and the melancholy of metropolitan isolation. Psychologically, blue evokes a sense of "the blue hour," a transition between day and night where the city becomes a space of quiet contemplation and electric energy. Since 1950, artists have used this hue to capture the synthetic glow and architectural depth of modern life. Yves Klein's influence on the power of pure pigment paved the way for works like "Blue Night" (1951) by Paul Klee, while later, artists like Richard Estes utilized blue reflections in hyper-realist masterpieces such as "Telephone Booths" (1967). In photography, the world-famous Saul Leiter used muted, painterly blues to redefine the urban gaze in his iconic street scenes, notably in "Canopy" (1958). This selection explores how contemporary artists continue to use blue to map the emotional and physical geography of the city.
