Pastel colors: pale pink, mint, peach, light blue and other delicate shades. These colors give the works tenderness and femininity.  Pastel Transitions: Art Nouveau often applies smooth transitions between colors, creating an atmosphere of softness and harmony. Symbolic Colors: For example, blue can be associated with dreams and fantasies, and green with nature and harmony. Contrasting colors: In some Art Nouveau works you can see the contrasting use of color – red-blue or orange-blue. In this way, dynamic and bright compositions are created. The use of gold and metallic shades: gold and metallic colors (bronze and copper) add luxury and sophistication to Art Nouveau pieces. Experiments with color combinations: artists often experiment with unexpected and unconventional color combinations to achieve a certain mood in painting. The main thing in Art Nouveau is expressiveness, so creators in this style freely interpret colors in their works.
