In this client project, I tried to rebuild the visual identity of the polyu choral society – POLYCHOIR. I started with building the logo for it. The design goal is to associate audiences with music at their first sight, so I applied some musical elements like musical notes, rhythm and so on to construct the logomark in different layouts. In the final version, I embedded the initials of POLYCHOIR – P and C into the most typical musical symbol – clef and sharpened the entire logo to depict the intrepidity of this society. Modern typography is selected for the logotype to harmonize with the logomark.
