The task of the project was to create a variable communication system, which will serve as a guidepost for individual events and projects of the symphony orchestra. Due to the long name of the organization, the logotype was shortened into the abbreviation PSO, which is suitable for independent communication and is variable for different occasions. The colour differentiation of the last letter corresponds to the colour stylization of individual events. At the same time, the meaning of the logo remains clear despite these changes. Intentionally deformed element of the letter O is then applied to all graphic materials across the communication spectrum.
