The Science Behind Union Pacific Yellow

Scientifically, Union Pacific's choice of yellow is based on its high luminance, which makes it one of the most visible colors in the spectrum. This is particularly vital in terrain where visibility can be challenging, such as in dense urban areas, heavy fog, or harsh weather conditions.

Moreover, yellow is also one of the first colors the human eye perceives, further enhancing its utility in rail transportation. This is because the human eye has more cone cells for short-wavelength (blue) and middle-wavelength (green) light, which is what allows us to see yellow more quickly.
