    I’m pretty sure you can still fly a plane even in black and white. WW2 pilots did. /s

      Wiley Post flew with one eye, even.

      Though, he did die in a plane crash in a plane he was piloting, taking Will Rogers out with him.

            Maybe…

            It gets less funny if 80% of the comments are missing the sarcasm/joke though. It can happen even when the sarcastic remark is obvious (usually because the first reply took it seriously, which set the trend for the subsequent discussions)

            That’s why I put a /joke or /s mark preemptively in my comments.

        It’s a 74. But parts of the 4 are a different shade so you see 71 if your color vision is different.

          I can see it, but only when I look at it real hard, if I just take a glance it’s 71 for me. The different shade that part of the 4 is made of really throws me off for some reason

          So to get this straight, I see the other green but it’s like a sludgy brown-lime green as compared to the full on greens. It contrasts so much from the full greens that you actually have to look for it rather them glance.

          Is that how it’s designed to look? Because if so it’s less a test and more a trick. Otherwise I may have learnt something new about myself

          You guys have to be memeing. I can sort of see the 4, although it’s pretty subtle. But there’s no way that’s a 7. It clearly curves at the top, like a 2.

          Edit: Ok, nevermind. I just loaded up the image in an image editor and shifted the hue a bit. I can see the 74 then. I knew from previous color vision tests that I had somewhat less than average color vision, but I didn’t think it would be this striking.

          Edit 2: Oh, and here’s the edited image, for others who might have trouble seeing it (I hope you won’t have trouble with this image, too):

      I had a moment where I believed I was colorblind because I was toying around with iOS accessibility settings and one of the colour filters looked exactly the same enabled as disabled when I tested it. Good times.

    Can I just tell you how much I hate those Ishihara tests? I don’t see shit in that OP one (which was exactly what I expected).

    Once upon a time, Panasonic did a print ad for one of their new color printers that was a dot test that read “Panasonic”, with nothing else on the page. Not super-effective advertising - although I suppose color-blind folks weren’t necessarily the target demographic…

        Yes, they do.

        I kinda hate them because non-colorblind people generally say one of a few things when conversations about them come up: “OMG do you really not see any numbers on there? It’s so OBVIOUS”, “Wow… so what color is this [insert random obvious thing]?”, or “So you’re colorblind? How do you deal with traffic lights? LOL”.

      I’m not color blind and never realized that these are made to show different numbers for those who are and are not. Never paid any attention to it, but now I can clearly see the 74 is made of two different colors/shades. Huh.

    I can confirm that I see both an orange car and a 21. I’m not colourblind in the "I can’t see any colour " way and I can drive a car and see traffic lights without any problem but I do percieve colors differently enough to get in arguments with friends and family about the colour of stuff. I think it’s called deuteranomaly

    Edit :the more I know!

      Colourblind isn’t the complete absense of colour, e.g. everything looks black and white. With deuteranomaly, you are the actual textbook definition of colourblindness… There are different levels of it, but all can still perceive colour - it’s just whether the difference in colour of the spectrum is detected correctly.

      Deuteranomaly (/ie) is the reduction in reactivity of the red-colour receptors. That means your perception of orange/red/brown is less than those with normal vision.

      For those with normal vision, this is a great chart. But, if you’re colourblind, it’ll be more confusing for you, sorry!

          If I were to guess, it might be because purple isn’t a wavelength of light, it’s like a glitch in how we perceive light with the two cones opposite to each other in the spectrum being stimulated at the same time without the middle one.

          For any practical purposes in every day life, purple is a color, it just doesn’t exist outside our perception.

            I’ve actually gone really deep on this and the graph they’re shows the mechanism at work. “Purple” strictly doesn’t exist, you’re right, but also wrong. Violet activates essentially the same receptors, “blue cones” in the retina are mainly only sensitive to blue/violet, but if you look at it, the “red cones” actually have an uptick at the extreme of blue (into violet), so when just blue is activated, we see blue, but when we see red+blue, we see it as violet/purple, because if our eyes were seeing actual violet, that’s what would be activated.

            Purple as red+blue, doesn’t exist, it’s literally a hack to trick our brain into thinking it’s seeing Violet, when it is not.

            EDIT: this is a far better explanation than anything I could come up with, and demonstrates the phenomenon. https://jakubmarian.com/difference-between-violet-and-purple/

      You are actually textbook definition of colour blind. What you have is deuteranomaly which is red green colour blindness.

        Even though I know the dress factually is blue and black, I think a white and gold version should be made, because it’s pretty.

        And it should also be photographed in such a way that it appears to be blue and black.

        Night owls tended to see the dress correctly.

        It has something to do with how good people are at looking at visual keys in the picture to determine the color.

        All colors are pervieved relatively. Vsauce on YouTube has a good video on this
