4 Introverts vs Extroverts
But while our preferences may be evolutionary, there is a distinct difference in how different personality type responds to color. As stated in the last slide, each color has a vibration. That vibration is associated with the strength of boldness of that color.
This is how personality plays into it, according to Rose. Extroverts, who require a lot of stimulation from their environment, will gravitate toward stronger colors, like Rose Gold or Red. On the other hand, introverts, who need less external stimulation, will tend to prefer more muted colors like Silver, Black or Space Gray.
