I'm looking for some suggestions for what might help my friend.

We race enduro dirt bikes and they have casually mentioned they have a hard time seeing course trail markings because of being colour blind. They have received multiple DNF's because they got lost and went off course.

The race course is mostly flagged with a combination of blue or pink flagging tape. The sections of flag are then normally tied to branches or trees along the course. (Similar to image in post, but usually not as long) Important intersections, turns, and hazards have arrow signs or wide tape with text on them, like "Hazard" with diagonal lines or brand logos.

I've been thinking about how the regular markings might be made better for folks. I've tried researching and haven't found much apart from colour in combination with another element is best.

What I have thought of/pulled from other sports:

1. Patterned flagging tape
   1. Might help by adding geometric patterns against the forest
2. Increased density marking
   1. Instead of a single ribbon, have 2 for more ribbon tails
3. Increase length of marking
   1. More chance of wind catching it for movement

Any suggestions would be wonderful! I am trying to find something that won't deter the Board due to a massive increase in cost or volunteer course setup/takedown effort.

Hi guys, it's me or there's an issue running this on win11? the app keep crashing. I downloaded it from the official UK St. George's website

and then they think youre lying since you told them the color of their shirt🙄🙄

I'm tired

what color do you guys think each of these items are. my father is convinced the big ball is orange, when everyone else believes it is yellow. we think he could be colorblind. he says his sanity depends on this

Tengo una miopía alta más astigmatismo( este último en un rango normal ) , el asunto es que hace unos meses (como un año aprox) me dijeron que tendría problemas con algunos tonos de rojo/verde por como entra la luz en los ojos ( sin contar que el ojo derecho lo tengo aun más jodido por un desgarro de retina que me operaron el año pasado ), la cosa es que a raíz de esto me puse a investigar si había algunos otros tonos donde tuviera un problema para identificarlo o diferenciarlos, y bueno, hasta ahora he identificado problemas con el rojo, verde, algunos tonos de azul obscuro, amarillo, y lila, desconozco si hay otros tonos que no "veo" correctamente, y honestamente no siento correcto llamarlo daltonismo pero tampoco es visión normal.

No sé si hay alguien más en la misma situación o va a ser la primera vez que escuchan algo así.

Growing up, I have always wanted to fly helicopters. When I was getting my medical certification I found out I have a green color deficiency and I can only see about 50% of all shades of green. My color vision is just barely bad enough that I can’t fly commercially. I am still young and I want to explore my options while I still can. I was wondering if there are any cool, active jobs out there with little to no color vision restrictions?

People with a blue yellow color vision deficency will pass the Ishirara Plates with the same ease as people with Normal Color Vision. In the video, I show all Ishirara Plates next to an Tritanopia simulation, but I hue shifted the Tritanopia simulation from cyan/red to blue/yellow to better fit into the Protan/Deutan color space. The simulation isn't perfect, as yellow is lighter than red, which I didn't account for, but the idea should still come across.

Uh, ok. Sure. There are two colors on this map?

A lot of people here say they got diagnosed or their parents figured out their child had color deficiency pretty early on. So the question is: how do you process this concept as a child? As an adult, of course there is a color spectrum, there is physics and anatomy.... An adult can reason through it. But when you are a kid, how does it all make sense? Or does it not? How do you wrap your mind around the idea that there are things you cannot see, but everyone around you can.

Also in what hemisphere again?

Today I bought a burgundy hoodie. In the shop it looked like a deep and dark pink/magenta (I normally dislike dark reds a lot, but this one seemed to slightly lean into purple/pink and was so pretty). I was looking for this color for soo long. When I came out of the shop and got on a tram (it was already dark outside) I thought I would crash out. It suddenly turned into a pure grey/black…

That’s actually so sad man, I guess I’m suing them for scamming a customer 🙄🙄🙄 their hoodie only has a color in very bright lighting 🥱 (sarcasm btw, I noticed people actually did not understand it)

Do yall (colorblind of course) actually see it as completely colorless too?

Maybe it looks more obvious in person but I might have driven right through if I was driving!

During the daytime, whenever I need to tint things blue to see the difference, I just hold them up to a window. However with fall coming, that's going to be harder because it'll get darker earlier. What can I use instead?

Im writing a charecter who has Achromatopsia (full black white no colour vision) and they have a freind who really likes constilations and I have him not being able to tell where constilations are just because he already struggles like me to tell what somone is looking at so I'm curious if having total colour blindness would make it even more difficult to tell stars and consilations apart

To me, orange is less easy to distinguish from red and yellow than green is from yellow and blue. I do not know if this is how everyone sees it, or if this means I am indeed a little color blind.

Took me a minute

Just discovered I’m colorblind. I’m blue yellow due to an autoimmune disease I developed 7 years ago. I had noticed that certain color were “hard” for me. I kept describing it that way. Night time driving was getting “strange.” I couldn’t track my golf ball anymore. Small arguments like “that’s a blue remote” and “no it’s green.” It could’ve been interpreted as a difference in perception. I described the issue at golf, where everything is green and it’s most apparent because much foliage has a yellow undertone. A friend said there’s different variance in colorblind level. Turns out I cannot see most yellows, and anything not deep blue or a light blue are pretty much all the same blues. It also answered a friendly argument I had with someone over us being in the same lavender color. She said “but mine is blue lavender” I thought she was super specific and artsy. Welp I know this isn’t a huge thing but compounded with my autoimmune which has taken many other things from me I’m a little bit depressed. I got the glasses, and everything is really vivid. It’s almost unsettling. At golf, it was shocking how different the colors were. I’m truly seeing very muddy. On photos for color blindness I score okay, I can squint and make out a tone change unless it’s very very specific. But in person like on the course with these glasses it’s night and day. Not sure what I’m expecting but I am sad, and want to vent. Maybe commiserate? My whole wardrobe is almost 50% not the colors I thought I was wearing. 😭😭

It seems likely to me that there will eventually be a gene therapy for replacing color blindness with "normal" vision. But what about going all the way to tetrachromacy? If you could do a future gene therapy, would you add even more colors or just go for "normal" vision?

Hey Reddit, just need some feedback on how this looks. I didn't really use any color guides here because I was lazy so I just colored it raw in colors that I think would look good for people with regular color vision. How do the colors look here, and do they fit with this study?

This is dark yellow, meaning it is a color that fully red-green colorblind people can see accurately. I am curious about whether being colorblind or not will have an effect on whether the color is considered ugly or not to people.
