Visual repertoire does not come only from trends. It comes from observing systems, brands, typography, grids, behavior and culture. Good books help create better criteria for evaluating design.
For those working with creative production, branding and resizing, it is worth studying both identity and usage. A strong brand is not just beautiful: it needs to remain recognizable across dozens of formats.
A few useful reads to start or revisit:
- Designing Brand Identity, by Alina Wheeler.
- Logo Modernism, by Jens Muller and R. Roger Remington.
- Grid Systems in Graphic Design, by Josef Muller-Brockmann.
- Thinking with Type, by Ellen Lupton.
