Lifestyle: what is the most visible colour?

Sometimes, during tutoring, the key is to ask the really interesting questions, whatever the topic. The tutor brings up one he recently wondered.

What is the most noticeable colour, by day, anyway? Red? White? Apparently neither, but rather, fluorescent green/yellow. Perhaps it’s no surprise you see it on reflective tape and even fire trucks and hydrants.

Apparently the human eye is particularly tuned to that green/yellow colour we think of as fluorescent green (or yellow). Hence, its adoption.

For night visibility, the opinion is divided – more on that in a coming post:)
