This Is the Most Visible Color in the World

An orange vest isn’t the best way to stay visible in traffic anymore. This extremely bright green coat is. The Nano Meter 555 Midlayer jacket, made by the outdoor sports retailer Vollebak, is designed to be the most visible color ever, as Co.Design reports.

The green color was created by analyzing the way the rods and cones in our eyes are stimulated by different wavelengths of light. The company found that the human eye is most sensitive to light at a wavelength of 555 nanometers—a bright green. It stands out against any road you’re biking down or any mountain you’re climbing, allowing you to remain visible even from high in the air.

Vollebak’s garment also comes equipped with special reflective markers that make it easier for others to see you moving in the dark. The bright green might not show up in the middle of the night, but the reflective discs will, and their placement on the jacket is designed to allow other people to recognize you as a person in a quarter of a second—even if they can’t see the actual outline of your body.

Ideally, you shouldn’t need to wear special reflective clothing while you bike down the street, but if you do want to stand out on the road, this is the way to do it (though studies vary when it comes to what kind of high-visibility clothing is actually useful to cyclists). It could also be useful for hiking or backpacking, since you could easily be seen by a helicopter if you needed a rescue.

Just think of how much more fashionable your local crossing guard would look in one of these.
