The visual identity of Théâtre Les Arènes features a bright, solar yellow as its dominant color, evoking energy, creativity, and visibility. The communication design is applied across posters, t-shirts, tote bags, badges, and stationery. A key graphic element is the use of the theater's half-moon logo shape—echoing the architectural form of ancient arenas—which frames current production visuals and brings a dynamic rhythm to the layouts.

This bold, circular motif is contrasted with a clean, structured typographic layout inspired by Swiss design, offering balance between contemporary vibrancy and classical clarity. The result is an identity both striking and elegant.
