    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”.

    It doesn’t say anything for me, it’s an odd shape of different coloured orbs and yes i am confirmed colour blind. Red green, i keep forgetting what it’s called.

    Reminds me of that one post where op discovered he was colourblind when he sorted characters by colour and it being obviously wrong.

      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.

      Not colorblind.

    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!

        So everyone can see a form of blue, most being royal blue? That’s super interesting because there’s a saying in art, “If you can’t make it good, make it blue.”

          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/

          It does include purple, it’s a little bit before the 400nm mark.

      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

      It’s funny. If I look away, I can clearly see 21, but if I look at it, it disappears.

      (I am colorblind, by the way, but not red-green colorblind.)

      If you’re being serious you might want to go get checked, because it’s possible you have some color blindness.

        I have been checked, and I am definitely officially color blind. I’ve known this for years and there is no doubt about it.

          I apparently have reading comprehension issues. Ha. I have no clue how I missed the end of his statement. I think I read “am I colorblind.” Gotta slow down and read.

      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’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.

        You might hate the /s, but it’s really easy for peolple to miss the sarcasm (no matter how obvious it is!) when everything is in text.

            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.

    Is it bad that I glanced at it and also thought it was 71, and had to actually consciously pay attention to the colours to see the 4?
