Can you see pink?


  • I survived the hour long Uno hand

    Pursuant to a conversation in the Lounge, I mentioned that I spectacularly bombed a test to see if I can see the color pink well. This is that test: https://www.buzzfeed.com/lorynbrantz/how-well-do-you-actually-see-the-color-pink?utm_term=.py4m2blag#.pxNZvmj83

    An interesting test, but I see two small issues with it:

    1. It's highly dependent on the colour fidelity of your monitor
    2. This:

      How can it be perfect when I got two of them wrong? :confused:


  • I got 7 of 8. Missed one of the circles. It took a bit of doing and technically I couldn't read the whole word at the end but I saw the first letter clearly enough to eliminate the others.

    This reminded me of those magic picture things. To see stuff I pretty much had to be looking right at it and not too sharply focused to be able to pick up the differences. Once I knew where the shapes were it was usually easier to see them.

    Yeah, my monitors are noticeably different in their colour reproduction. I got 6/8 (missed a shape in a counting one and couldn't see one they were asking about the colour of). Might try it on my other monitor and see how much easier or harder it is

    Apparently a lot of people see three circles instead of four. I see none :/ Even on a different monitor than my usual, though no guarantee it's better calibrated

    As an example: There's an image where the background is #FF66B6, and the triangle within is #FE65B5, a difference of just 1 in each of R, G, and B. The same difference applies to that fourth circle.



  • 3 out of 8 :disappointed:

    Or rather, 2 out of 8 TBH, because even though I counted the right number of circles that one time, they were not where I thought they were. :smirk:

    But my computer is currently connected to a TV that was reddish even before f.lux, so whatever.

    Back to the OP, when I was still in construction pink paint was used to do layout on dirt but due to my colorblindness I could not see it. Not enough contrast to our light colored clay around here. If I was walking around, looking straight down on it I could usually see it. Sitting in the seat of a dozer and looking at an oblique angle and it was pretty much invisible. To compensate I would layout all my work in blue paint which normally is used to mark water lines, which caused some confusion and amusement at times.

    So one day the owner of the company I was working for at the time got out to a job and started laying everything out in the usual color. I was tied up at another job so by the time I got there he had almost all of the layout work done. He had probably spent 2+ hours out in the heat marking all of the foundation lines.

    :man: "Almost done, you should be able to get right to work."
    polygeekery -ahem-
    :man: :What?"
    polygeekery "Pink paint?"
    :man: "Yeah...why?... Shit. Goddamn it you colorblind bastard." -flips can of marking paint in the air- "Do you have any blue paint with you?"
    polygeekery "Always."
    :man: "This place is going to look like there is water main all over the place. Make sure you wipe out all of the marks when you are done or the other idiots around here will be completely confused."



  • 5/8. Color difference between my two screens was way more pronounced than the differences in the pink colors. Granted, one of the screens sucks and it feels like it has like 20 gray levels tops.

    Same here (red/green colorblind). The only one I got wrong was the circles one that Yami said a lot of people answer 3 instead of 4.

    Summary: I call bullshit.



  • @Yamikuronue Some of these shapes were (barely) visible on my phone and not on my work notebook



  • Six out of eight. I missed the upper left circle of the [deleted for spoiler reasons] and couldn’t make out the triangle so I thought there was no shape there at all.

    Happily, this means I can keep playing with my Space Marines without confusing them for someone else's:

    either that or they forgot to handle the case where someone failed to get a single right answer? i mean the P() value of that outcome is only 1.525878e-5 so even guessing randomly it's damned unlikely



  • @Gurth You could have gone all the way and made a Pretty Marines army. Though personally I find the Sleepy Marines to be the most entertaining chapter.



  • @Yamikuronue I was convinced this was a practical joke, but:

    0_1497289636048_Untitled.png

    I can actually see the hearts if I dick with the contrast and brightness of the image.

    That said, I think there's one of two possibilities here:

    1. The hearts are purposefully too faint for 99.999% of people to see
    2. They're actually testing monitor color calibration, or perhaps backlight brightness, more than anything else.

    Either way I certainly don't feel bad about not seeing any of the pink-on-pink images in that post.



  • @RaceProUK said in Can you see pink?:

    Oh dear.
    The images are JPEGs.

    jpegs that get re-compressed as .webp (at least to Chrome users). So double-jpg.

    That's why the one I adjusted the brightness and contrast on is so jaggy. Either JPG or WEBP or both assume the colors are too similar for people to notice and so take "shortcuts" when compressing them.

    Effectively perfect may not necessary mean you can differentiate minute shade differences.

    Couldn't really see the hearts, but could tell in glimpses they were there. Missed the circle in the top left, but otherwise counted correctly.

    A kindred spirit! They just give me a headache; if I defocus the way the instructions say, I just can't see the picture at all. I guess I rely on having both eyes see the picture in order to focus my eyes on it at all (and no, I've no idea how that works, but it gives the sanest explanation I can think of for why I can't see those things).

    If someone wants me to see a 3D picture, they need a different display tech or I just won't see it at all. (Circularly polarised light cinema projection was a great invention; much better than what went before at that scale of deployment.)

I guess I rely on having both eyes see the picture in order to focus my eyes on it at all (and no, I've no idea how that works, but it gives the sanest explanation I can think of for why I can't see those things).

    If you have, say, 2 identical dots, can you shift your eyes so that it looks like 3 dots, with the one in the middle composed of both dots overlapping? That's basically what's happening.

    :fa_plus_circle:                  :fa_plus_circle:

    There are two ways of doing it: one by gazing off into the distance and letting your eyes drift apart (diverge), and one by going more cross-eyed (converge).

    For the convergent method, blurriness can be an issue; naturally when your eyes focus on something way off in the distance, something close will be blurry. Your eyes not only moved to point at it, but they also changed their focal distance in anticipation of needing to in order to see it clearly. It can help to have two clear images with high contrast to the background so that you can identify them even when they're blurry; once you get the two blurry blobs to overlap, it takes some focus to actually get your eyes to readjust for the distance so that it's clear.

    The hardest part about the cross-eyed viewing is getting your eyes to stay cross-eyed the correct amount; I could go cross-eyed but it was way, way too much. I found it easiest to just go cross-eyed first, then slowly let my eyes gradually drift back toward their normal position, trying to catch and stop them at just the correct angle when the dots converged.

    Once you can get two dots to overlap using one or the other method, you should in theory be able to get the hang of the Magic Eye-type images. Note that pictures are made for either convergent viewing or divergent viewing, and using the wrong method will result in the image's depth channel being reversed: what's supposed to be nearer will be farther and vice versa.

    I don't have good vision.

    I think vision and color differentiation are 2 independent things.

    I have such poor vision I don't like to swim without my glasses but I could differentiate the pinks.

  • Discourse touched me in a no-no place

    I got the one about the blue circle right.

    I also got the one with no internal shape right (though given the prior results I couldn't have proven that).

    I think my phone screen is fucked, so I'll try again when I get to real displays.

    As an example: There's an image where the background is #FF66B6, and the triangle within is #FE65B5, a difference of just 1 in each of R, G, and B. The same difference applies to that fourth circle.

    In the LAB color space, color #1 is approximately
    L: 65.0736565677347
    *a: 65.7690412636606
    *b: -12.4079957334033

    And color #2 is approximately:
    L: 64.7352287083402
    *a: 65.7794126216639
    *b: -12.3627455985462

    These two colors have a Delta E of 0.2794.

    The smallest difference in color that you are supposed to see is somewhere between a Delta E of 1.0 and 2.3, so theoretically you should not be able to see a difference between the two colors. Not even with a really good monitor. If you can, then something else is going on.

    Yeah, I took my time to see them. Cleaning my monitor, looking from different angles, moving the browser window. Increasing, decreasing the size of the image.

    I'm sure I would have done poorly on my phone.

    @anotherusername I know the theory of how to get the stereogram working (and I once wrote a program to create them, ages ago) but that doesn't mean I can actually see them at all.

    Another possibility is that you have one eye that's much more dominant than the other. That would make it difficult to get the image to converge properly.
