Realization of the graphic charter of the National Theatre of Toulouse. Work carried out in a one-week workshop. The logo was designed with inspiration from the architecture of the building. This simple and uncluttered logo increases its communication efficiency. Then we chose colors that work as a duo to represent the different events proposed by the theater. We thus find these duos of colors on all the declensions of posters, flyers and tickets. We have also associated a 3D shape to each duo of colors so that each event is recognizable at first glance.
