Why Are Safety Vests Yellow?
You may wonder why are safety vests yellow. The answer is simple: they increase the visibility of the wearer. The human eye does not readily detect blue because it has an undesirable wavelength. On the other hand, yellow is a color that attracts the attention of the human brain. That's why most warning signs and hazard symbols are in this hue. The yellow color has many other benefits as well. It can help people recognize and avoid dangerous situations where they might need to use high-visibility clothing.
