hi-vis lime yellow is definitely the best in my opinion

genec

The lime yellow is supposed to be the best, but I have a vest that is both... I added blaze orange to a hi vis yellow vest... in the thinking that any one single color can be lost in certain backgrounds, so contrast was the most important thing. My helmet is black and white for the same reasons.

Wogster

Of the vests at the link, one has both, and I think that would be most visible.

+1 You need to outline the human form by using a different color. This is why hunters try to hide or conceal their outline.Some hunter use blaze orange(Deer can't see orange) in a camo pattern just to hide their outline but still be visible to others. Hunters want to blend in cyclist want to stand out.

Ahh but if you get a blaze orange hunting jacket then you can wear it in the winter while cycling. Dual use! And if you have an Xtracycle then you can pack in and pack out on the trails while still being environmentally concious.

EDIT: and according to a bow hunting instructor I had years ago Deer can't see either lime yellow OR blaze orange... for some bizzare reason they just show up as dun colors to deer.

For most purposes the hi viz yellow is better. However, if you are riding into bright sunlight, I think blaze orange is better because it's further away from the color of the sun in the drivers' eyes.

I own both.

This is precisely the reason why we need smartcloth that can color-change at the click of a button a la "Snowcrash" by Neal Stephenson.

One jacket to rule them all and in the darkness make them visible.

I've got both, and have taken to wearing a blaze orange 10 mile-cloth surveyors' vest for middle of the day trips, and think the high vis yellow shows up better at nighttime or dawn/dusk.

I think the blaze orange works better in full light but bad visibility, and the neon yellows in dim light conditions. My experience and my observations of roadworkers, etc....

The reason for that deer have no predators of that color, So they have no need to see that color. I wear blaze orange vest in the winter If we have snow on the ground it stands out better against the white back ground

deputyjones

Agreed. Yellow will remain visible longer as light fades.

I wear my blaze orange one during the day because I think the orange color stands out better against the green foliage. during evening/night/poor visibility conditions I prefer the lime green with reflective tape because the green shows up better in headlights than the blaze orange one.

I don't see much color and didn't know the alert-shirt had lime-green in it...can only see yellow in that shirt. It would seem that Red should be an option.

ranger5oh

Its been a proven fact for years that the lime-yellow color is more visible than the old orange.

There are ninja cyclists.

You, my friend, are a neon tiger cyclist!

When I see orange, I think traffic cones, and barricades, not human. The high-viz really seems to catch my eye. I was impressed enough from seeing it at various construction zones that I bought a high-viz shell for winter, two high-viz jerseys for summer and traded in my orange traffic vest for a high-viz one.

CommuterRun

I don't know why it's called lime. Don't believe I've ever seen any part of a lime that was that color.

Anyway, that's what I wear. But I typically only wear it at night for the orange reflective strips on my vest. During the day I normally just wear a white t-shirt. White showing up the best against the widest variety of backgrounds, under varying light levels. It very rarely snows here. Even more rare to get enough to stick.

They, like you (you in natural low light at dusk, they all the time), are 100 % colour blind.

I have the Alertshirt vest and the sweat jacket in ANSI lime and I constantly get comments on how bright they are. Several people have even told me it hurts their eyes!

This chart is a real [ahem] "eye opener" -- it shows yellow-green is more than twice as visible than orange:

Human Eye's Response to Light

I found the text interesting. I did not know that under truly dark conditions, once the eye is completely dark adapted, the eye's response changes and blue-green becomes the most visible color (although it will look gray).

Frankenbiker

Of course, proper bicycle safety attire on Remulak requires wearing both an ANSI lime vest and an orange traffic cone.

Wow, not much of a content in that poll !!!

Check out www.pedigreen.com. We carry the hi-viz yellow/green colored items of apparel and lots of accessories. I can tell you our best sellers are the two tones items. T-shirts and vests that have the yellow/green body and orange (black even) used as a contrast. It has the WOW factor.

I voted for Hi-viz yellow. I do also think that blaze orange is the best against a snowy back ground especially in very sunny conditions.
