I was going through multiple car/bike apps across the world and there was striking similarity that most of them use a shade of either red or orange. I wanted to understand the psychological motive behind it.
The color orange is associated with extroversion, enthusiasm, energy and motivation. Moreover, it's quite noticeable. In the context of transport, orange could represent a positive, "adventurous" vibe which evocates traveling, meeting new people and sharing experiences.
