Colors & Typography

## Visual language

We approached the selection of the color palette and fonts by balancing brand identity, user experience and accessibility.

For the CarFin - Car Search AI Assistant example, we selected **Urbanist** for its clean readability and modern tone, helping users focus on essential content without distraction. The **accent lime color** improves interface scannability and supports energy and action-oriented behavior across primary CTAs. 

These choices reinforce consistency across dashboard, mobile, and website experiences. The goal was usability and identity, not decorative design.
