Simply put: every color creates a specific feeling, and the brain interprets it as safety, trust, urgency, or motivation
Colors affect three major dimensions:
Perception:
Does the design feel professional or chaotic?
Emotion:
Does the user feel trust or anxiety?
Decision:
Will the user take action or ignore the interface?
