When I was a teen, I took an EMT class. You could be red/green colorblind, but NOT blue/yellow. Why was one okay and not the other? If you can't see blue or yellow, you can't see if someone is cyanotic (not enough oxygen) or in certain stages of hypothermia. You also couldn't see if they were jaundiced, indicating liver problems.

Color blindness accessibility is a big topic of conversation in game development, especially for how red is used to indicate so many things. My husband and a colleague were discussing the game Control, a game which is largely greyscale with moments of red indicating importance. His colleague is color blind and found the experience infuriating. It's really important to not forget for the rest of us. It's also why Ticket to Ride has unique symbols with every colored card, so you can track symbols if you can't see colors.

I'm a train conductor in the US and color blindness is taken very seriously still. We have to take a physical upon hiring and every three years after which has a color blindness test. A coworker was found to have his sight be red deficient. The railroad set up a test signal where an employee can change the aspects (colors) with a switch and used this to test to see if he can tell red, yellow and green apart (solid and flashing, different combinations of two) from certain distances. He failed the test at the furthest distance (quarter mile) required. Him being a railroad nerd pointed out that the signals used for the test were only rated for 1000 feet, so they sent him to test at another location. He failed again but the test used the exact same model of signal. He tried to fight it but unfortunately his union didn't want to back him up and he was medically disqualified from the job. What's wild is there's no standardization on railroad signals in the US. A green aspect over a yellow can have completely different meanings between two adjacent railroads. Employees are required to memorize signal names (proceed, stop, approach, etc.) and associated rules with each verbatim for each host railroad they operate on. As you can imagine, this can and has lead to errors caused by the human factor. More relevant to your video, the Pennsylvania Railroad devised a radical new signal design in 1915. All the signals were a yellow color designed to cut through fog and be very visible from long distances. The design mimicked semaphores. A straight up and down was equivalent to green, diagonal to yellow, and horizontal to red. These position signals were probably the first color blind friendly signaling system. The signals used today on Amtrak's Northeast Corridor and many parts of the eastern US (NORAC signals) are derived from the Pennsylvania Railroad signals, but with added color.

Folks there stressed that the name of the city was pronounced "Lin - shurping" (the ur should be soft to get the umlaut o) rather than "Lin-Ko-ping". The last part of the name is a cognate of the english word "shopping" and it refers to a market town. There is a string of cities in that area, all ending in "koping". They are all market towns and it is a beautiful region of the country to visit.

Unless you want me to make my eyes work together? And they just told me I was wrong and asked me to answer again. So I said yeah (if I make my eyes work together) it's on the picnic table. I think an eye doctor would have seen I have astigmatism but the school nurse doing hundreds? Of these exams gave me a clean bill of health. We also took the test in groups so that you could copy someone else's answers.

My Dad was rejected as a pilot in the airforce due to his color blindness, he stayed as a meteorologist for another 25 years and was always a touch bitter about it all. When I was hired as a railroad conductor and eventual engineer I was definitely worried I'd be in the same genetic boat. Thankfully I didn't inherit that myself, given that all I ever wanted to do was run freight trains. Signaling systems on railroads are far more complex than most people would probably assume, and color combinations definitely require a thorough understanding or else carnage inevitably ensues. Even where I work in western Canada there's literally hundreds of different combinations and sequences we have to memorize over hundreds of miles of collective territory ranging from blind curves through mountains in near blinding wintery conditions and everything else in between. I'm sure it's even more intense in passenger service on 100+ mph track the world over. Great videos, glad I came across this channel. Cheers.

Between the amount of objects in nature which signal they are poisonous by being the red thing standing out among a sea of green, and the amount of fruits and vegetables which signal they are ripe by changing from green to some shade of orange, red, or purple, I have a really hard time believing colorblindness has only presented a problem post-industrialization. Also, the direction I was expecting this to go was that the discovery of the role of colorblindness made the job more accessible because they introduced some feature like two red lamps and one green or different flashing patterns to make them easy to distinguish. But nope guess we'd rather just disqualify a huge chunk of people from having the job than make any small accommodations for accessibility. Never mind that the human eye being more attuned to luminance than chrominance means these changes would have made the signals clearer for everyone and thus easier to make out at a distance or in foul weather

It's not like ships and aircraft are even using the colours for their iconic "stop" and "go" meanings -- they just needed two different colours.

@@PhilEdwardsInc Actually, no, that makes perfect sense. D'oh! I've actually known the answer the whole time, but I never connected the dots before! A bunch of pieces just clicked into place in my head! Of the three primary colours, the human eye is least sensitive to blue. The numbers vary according to exactly which colour space you use, among other things, but when you convert RGB to grayscale, the green channel contributes 60-70% of the result, the red channel 20-30%, and the blue channel just 5-10%. And if you've ever been in a space floodlit in blue, you've probably noticed that it just feels dim, even when it's really bright. So if you need two colours of light for use at night, it just makes sense to use red and green, even in spite of disqualifying roughly 1 in 10 men and a small number of women, because we just perceive them better.

1:53 fun fact the red and green also shows priority. 2 boats or 2 aircraft that are heading towards each other perpendicularly can use the lights as effectively traffic lights. A boat passing from the left will show green which means you have priority, they see red on your boat. You can continue. If a boat is passing from the right you see red and you need to make corrections whether it be slow down or fly in a circle.

I am colour blind, but most people do not realise because, apparently, I'm very good at choosing colours, even though I usually have no idea what colour it is. According to tests that I have taken, my colour blindness is unusual. I see colours that others do not. Many might know the test where you trace a pathway of colour from "x" to "x". Well, I see pathways that no one else does. When I was being tested, eventually the tester gave me plastic sheets and a marker pen. When they checked the paths that I followed, they were all the same. Sometimes, it gets annoying when people find out I'm colour blind, and keep asking, "What colour is this?", "What colour is that?" I feel like screaming, "I don't know, I'm #!@^☆¥¿ colour blind", but I don't.

Hello, train enthusiast here. It's funny that you chose the railroad industry as the basis for explaining the emergence of color blindness as a distinguishing trait, because the railroad industry as a whole changed the ways in which they issued signals to try and correct the issues of unreported and untested color blindness, among other issues that they encountered. As a preface, In the United States there was very little uniformity in train operating and signalling standards from the 1850's until the 1900's, but most railroads began to install and operate Semaphore signals on most major lines starting in the 1870's (we adopted the technology from the British). These signals have both a colored signal, as well as a positional signal using a large wooden blade that could be positioned between horizontal and vertical. These signals worked well, during daylight hours, but unfortunately at night, only the illuminated part of the signal was visible and continued to rely on red and green as primary signalling colors. The semaphore signalling system lasted until the mid 1940's on most large American railroads, when maintenance costs were much more expensive on the mechanically operated Semaphore system, and were replaced with color changing signal lamps. Sometimes they were arranged in patterns so that they could be understood by anyone with the vision to see the signal, but oftentimes the replacement signalling system only had a single lamp that changed colors. This led meant railroads to begin enforcing mandates on vision testing and barring locomotive crew that were color blind. There is a similar story with hand held lanterns, but I'd need to do more research to be sure about it.

Your mention of VR vs motion sickness brings up another topic: medical testing for vertigo… The current tests for someone with vertigo are to induce vertigo and monitor the patient’s response. I liken this to someone with a possible broken bone, where the physician probes the break area with their fingers. If the patient doesn’t scream in agony, then no break. If they do, broken. I make this analogy because I have seen 4 ENTs over the years who all ran the same basic tests, along with a few extras at the more sophisticated facilities. As someone with chronic vertigo, these tests are literal torture. Efforts to correlate brain signals to those with chronic vertigo have been inconclusive. Given that the experience clearly is signal processing malfunction, it seems therein lies the way to diagnose the illness without subjecting the patient to torture.

I think an underappreciated aspect of colour-blindness is how a large part of it is a linguistic phenomenon. As it's not just a matter of confusing red and green, but rather having a different neurological sensation of them. While two things which are generally seen as red and green respectively are perceived as the same colour for a colour-blind person, the opposite is true as well; two shades of green will by a colour-blind person be seen as red and green. Thus, the confusion about what lingustically is red and green becomes muddied as the use of the two words don't match up with the experience visual perception of colour. One theory of why colour-blindness is as relatively widespread as it is, is that the ability to perceive slight nuances in e.g. green can be helpfull when foraging for fruit (think green grapes or gooseberries).

She was growing increasingly concerned as the deadline got closer, but I was completely unconcerned. When it came time to turn in our work on the case study I turned mine in and told her I conducted the entire project and wrote the paper the night before. She looked at me skeptically. Two days later she returned our work to us, and she pulled me aside to congratulate me. I conducted the case study on myself and my color blindness. I got the highest grade out of all the classes.

This crash probably also precipitated another important aspect of period rail safety when it comes to signals and using hand lanterns to communicate at night. By day of course you can see all of a signal, be it the semaphore arm or the exaggerated hand motions of the shunters whose directions you're following as a driver. At night though, with just colour to work with, there is another aspect to choose from, motion. Most railway handlamps can show red, white, and green. which can be 'stop', 'come towards me', and 'go away from me' respectively. With particular motion of the lamp, this can be turned into 'come quickly towards me' or 'go slowly away from me'. In all the manuals I've read though, there is a particular clause that usually states something along the lines of "Any signal erratically or improperly displayed must be taken as a stop or emergency stop signal." So that red lantern being waved frantically by the station staff would have been cause enough to stop in the 20th century. Of course now with the rise of affordable and capable portable radios in the 80's and 90's that had enough battery to last a shift (or at least most of it) the use of lamp signals at night for me has fallen by the wayside. Why wave a weak electric torch with a red lens around when I can just scream "OH SHIT STOP" into the radio? Much more effective and immediate.

Video game designers (I’m looking at you Lucas Arts) always use Red for foe and Green for friend- so much for playing X Wing Squadron! Traffic lights - yes they have positions that can be used but in the dark, a blinking colored light could be Red (full stop) or yellow (caution). Old Halogen street lights used to match the yellow of the yellow light- put them on a curve and that yellow light is nicely hidden. I was not diagnosed until 8th grade (60 now), when we were shown the Navy color blindness test, and me and another kid couldn’t see the numbers. When I was young, I was told I “didn’t know my colors". I learned to depend on other cues- that mysterious crayon box with so many duplicates was was at least labeled. 10% of the population has a color vision issue. Being careful when selecting colors in graphics, signage, is a type of inclusivity people should remember.

Amazing! As someone who generally gets motion sickness, I have never been able to use VR headsets and that tech. It makes me feel absolutely dog poop. I would love it if this becomes something we can "fix" or reduce the effects of in the future.

There was another problem with railroad signals in the past! How to distinguish between Home signals,Distant signals and interlocking signals,especially at might,and in bad weather! One pivotal train wreck,was the Abbots Ripton collision on the Great Northern[England],and the frozen signals and total lack of decent cabs,and brakes on the locomotives of the day! Lots of innovations came out of that! Another side line,on the same subject,is the use,of position/ color light signals in the US,and the fact that they are a derivative of PRR and B&O practice! Gets interesting in the complications over a period of 100+ years!! Thank you for an informative video,the things I didn't know! Thank you 😇 😊!

I’m substantially red-green colorblind and really enjoyed the video. I’ve always enjoyed talking about it, and it makes a fun icebreaker at parties. One thing I’ve heard but don’t know if it’s true or not is that colorblind people are better at seeing camouflage because they rely more on shades, movement, and texture instead of color. I heard they were used in WWII to spot aircraft carriers from looking down from an airplane. I’d like to know if this is actually true. For me at least, I’m almost always the person who sees wildlife first and can also find a handful of 4-leaf clovers pretty quickly.

for the motion sickness in vr, a major cause can be bad ipd adjustment. Palmer lucky said he couldn't use the meta quest pro (or whatever it was called) because of it's lack of ipd adjustment. This could cause a major barrier for people who's eyes are a slightly different distance apart than others, or even harder to adjust for, offcenter.

6:45 oh man watching out of the side of my eye and it looked just grey. Rewinding and double checking I see some green but not enough to make a number out. I know I’m red green colorblind. It’s somewhat mild as I’ve been able to tell red from green on most of the stuff in this video but there are definitely some shades of red and green that look brown to me.

Airlines and the military have solved this problem by just not allowing colorblind people to be pilots. My boyfriend is colorblind and is an editor. He uses color spectra, histograms, and lumetri to fix colors.
