For me i would want something as easy to find in the dark.
The human eye is most sensitive in the dark to light around 507nM wavelength. I’m not familiar enough with Pantone colours to know how to convert nM to pantone.
If the orange was a true blaze Orange, that would be my no-brainer pick. The color shown seems a little muted or rusty colored compared to a hunters vest for example.
But Orange, Coleman Green, and Blue are my choices.
I don’t think the colours in the renderings are very precise. If you look up ‘Pantone 21’, you’ll see a number of different colours, from the more yellowish one in the image to a more deep and reddish colour. The Pantone website itself shows a darker and more rich hue, but without a calibrated monitor it’s going to be difficult to tell exactly what it’s going to look like in real life.
Clear ano would be my first choice. Hard to miss silver in almost any outdoor/camping environment, even at night searching for a dropped/lost LT1 in fallen leaves using a cold white light. Otherwise, it's a tossup between red and orange. I voted for red just 'cause my wife's daily rider motorcycle is red.
