This looks like the red one is the hardest to see which would be unfortunate. Do you know if that is actually the case or is it just a side effect of how ever this image was created?
For humans with red-green colour blindness? I don’t know, you’d have to ask them! There are two types of red-green colour blindness though, people who lack red cones and people who lack green cones. I think the lack of red cones would make the perception more like the image above, whereas a lack of green cones would make the red light very visible but the green light a dim purple-like colour.
To make this image I used a website that was specifically for seeing a dog’s vision so who knows how accurate that is.
They are red/green blind…
Green traffic lights are slightly blue and this makes them easy to distinguish from the red light which will only ever trigger the yellow cones.
TIL Thanks!
