Also the most used color for SMBs (surface marker buoy) when scuba diving.
Interestingly, the bright yellow color usually means accident, while orange means regular decompression stop. I have seen pink ones but they seem very rare.
So I'm guessing people must think yellow is more visible?
I feel like there is a market for black "tactical" DSMBs for those dudes who really like to be special ops. And what better color than full black to mean serious operator! /s
I've seen plenty of yellow sausages that didn't mean emergency, I think that's location specific (I'm not sure where it applies). Most people I know pick the color based on personal preference / color matching the rest of the gear.
I've only done some diving in the Mediterranean (south of France). And the orange/yellow colors is the "recommended" advice I got from the local dive shops and the common understanding in the diving boats I've been on.
It a shame that CMAS, PADI or SSI don't propose a standard.
When you have high levels of confidence that the background will be ocean water and the weather is likely to be decent (or at least, decent enough to be diving), then it may be the case that yellow is more visible.
International Orange is designed to be maximally visible under as many different conditions as possible, so may not be the most visible in every single circumstance.
I hate this redirect nonsense as well. FYI though, if you tap-and-hold on the back button on Mobile Safari, you'll get a menu of the last 10-ish pages you were on.
As another poster said, just wrap it in whatever color you want. Costs start around 2500$, but that is far cheaper than a paint job and you can get any color you want, without worry about resale value. Personally, i like a matte finish.. something unheard of on production cars. Wrap is an easy way to the effect without repainting.
Yeah, matte colors seems to be a trendy thing these days.
Or IIRC I read somewhere, the current trendy matte colors aren't as much matte as lacking the highly reflective metal flakes of the popular "metal colors". So it's still a kind of glossy color.
If pure red is at 0° hue, and orange at 30°, then that engineering value at 3° is much closer to red. The other two at 18° and 19° better fit the reddish-orange description, still more orange than red, while safety orange is up at 28°.
If you ask people to select a pure red that isn't tinted towards either orange or purple, then on average they say somewhere around -15°. So 'computer' red at 0° is a little bit orange compared to that.
School bus yellow isn't the most visible color. There were some school buses and some customized buses that use(d) a fluorescent yellow-green color similar to safety vests.
Also, microprismatic reflective tape can retrofit a bus to be more visible under low-light conditions.
The article shows orange space suit. Interesting to me cause an orange suit on mars is probably not a good idea. A while suit on moon is also not. If you want to tell objects apart then maybe you need a per planet colour for a space suit ?
White is fine on the moon; every person who walked on the Moon wore a white suit. The Moon looks light colored to us on Earth, but its albedo is about 0.14, which is roughly the same as worn asphalt or dirt.
The orange space suits aren't worn in space, nor were they worn on the moon. Armstrong and Aldrin wore white, despite the moon being a bright gray. These are for recovery operations on Earth.
When it comes to colorblindness, it doesn’t make much sense to ask if a single color is recognizable. Color blindness is a difficulty in distinguishing between different colors - some pairs of colors that are visibly contrasting to normal sight may not be visibly contrasting to colorblind sight, such as red/brown, brown/green, and red/green.
There are three main mechanisms of colorblindness, corresponding to the three main types of light receptors in the eye: deutan (green-weak), protan (red-weak), and tritan (“blue-weak”, although this is not a common term). About three quarters of color vision issues are deutan, one quarter is protan, less than 1% is tritan.
When you go out into the world and start interacting with contrasting color pairs, both green-weak and red-weak color vision cashes out as “red-green colorblindness”, while blue-weak cashes out as “blue-green colorblindness”. None of these have issues distinguishing yellow/orange from blue.
Presumably this is actually the motivation for the international air safety color being orange, as it’s easily distinguishable from blue sky.
A further anecdote, I am also (slightly, not absolutely) red-green colour blind. Although I can distinguish between bright reds and greens, darker shades or in lower lights, I am unable to discern between reds and greens.
I'm not always aware that there is a colour I have not correctly perceived, and may simply think that a colour is 'brown', where others clearly perceive it as red or green. However, it's very rare that this causes me problems. I suppose electrical work in low light might be risky, but then I would be taking extra steps to ensure I did not screw up (increasing lighting, asking someone to double check before I touch anything, etc.).
Interestingly, the bright yellow color usually means accident, while orange means regular decompression stop. I have seen pink ones but they seem very rare.
