Turns out I really like working on those short briefs in limited time, it helps a lot with quick problem solving.
Anyways, here is what I did for the brief below! At first I wanted to use a classic serif font that would remind people of the fonts used in books, but it didn't quite work with the idea I had in mind. So I settled for this bold, still serif font.
The color palette reminded me of the warmth of bookshops, especially the beige that looks like used pages.
But enough explanations, I hope you like it!
