What is color psychology in web design?
Color psychology is a scientific discipline that studies how colors affect human emotions, perceptions and behaviors in digital contexts. In web design, this science is used strategically to influence purchasing decisions and optimize conversion rates.
According to studies by Nielsen Norman Group, The human brain processes chromatic information 60,000 times faster than text, making it the first element of evaluation that users make when entering a website.
Scientific foundations of color perception
Color perception works through complex visual processing involving multiple brain areas. Each color generates measurable physiological responses:
- The red accelerates the heart rate on average 7-12%
- The blue reduces the production of cortisol (stress hormone) in 23%
- The green increases the sensation of muscle relaxation
