Which Color is The Brightest?

Neon yellow-green is the single brightest color to the human eye, being the only color that perfectly aligns with our peak level of visual sensitivity.

As humans, our eyes are most responsive to a wavelength of 555 nanometers, which is directly in between neon green and neon yellow.

This bright colour serves a great purpose for the world as well, with it being used to create “high-visibility” in different fields. Construction workers wear it for safety purposes, firetrucks have been shifting to using it instead of the classic red, even road systems around the world using bright neon yellow-green paint.

It’s the loudest color there is, its entire identity is attention and visibility. Beyond functionality, it’s used in art, fashion, and many other creative mediums for its bold nature. Your brain can’t ignore it, so artists use it to really grasp one’s attention.
