   I also used the eyedropper function and there are variations of colors according to my computer. I've seen illusions like this before, but since this image is pixelated instead of a vector image, there are a few different shades of bluish-green/seafoam green

   Well, sort of. There are an awful lot of really blue pixels at the edges of the bands that 'appear blue' and yellowy-green pixels at the edge of the 'green' bands. No surprise that our low resolution eyes blend those.

   The implication is that an aqua color can appear bluer or greener depending whether it's next to orange or pink. This 'illusion' does not demonstrate this.

   An honest demonstration would use just the three colors. I bet the effect would be far less dramatic.

   I tried this with the thumbnail that was on the article when it was in the Upcoming line, and the colors were in fact different, but then I clicked through to the article. I thought someone was trying to fool me for a second.

   I just checked it in photoshop they are the same color only the image on here is pixelated but when you use the eye dropper you only get a slightly different code for the seafoam green depending on which swirl. As in stated in the previous post, had this been a vector image there would be no cause for disagreement.

   Ugh, brings back memories of a boring color theory class that I had where we made hundreds of these sort of images.

    I've used the phenomonon in my drawings. Never had a color theory class in my life.

    In photoshop, the blues and greens are definitely NOT the same colors. Which means, technically, the colors we're seeing in the above posted image are definitely different. In those pixels are spots of the same shade of Cyan, but the actual colors are, in fact, tinted differently. If the colors were truly the same on the monitor, zooming in would show them to be the same as well, and it doesn't.

    This may be true to the naked eye with an image actually printed using only one color, but it isn't true here.

    Very cool! I think the different colors you see @photoshop may be the artifact of the image being saved and re-saved for the blog post. Still - a very neat optical illusion.

    Sigh ... Yes, you will get slightly different colors if you use the eyedropper tool ON THE IMAGE ABOVE because of antialiasing and artifacting.

    Follow the link and look at the ORIGINAL IMAGE. The color is #00ff96.

    (BTW, if you're using the eyedropper tool in Photoshop, make sure you're using "point sample" and not a 3x3 or 5x5 average.)

    Nope.
    Green at 26 FF 98 in top right middle of band.
    Blue at 22 FC A2 in top left of middle of band.

    There is a fair amount of JPEG pixelation. If this were a PNG, it might really work.

    Close though.

    I wondered whether my resizing of and converting to a .png image would affect the colors. You should test the image at the link. But when you look at the zoomed inset at the link, they are clearly the same.

    zav - It IS a png image (maybe it was updated). But there is still distortion near the edges. The original gif on the linked page is fine, though.

    Not the same colour, checked in paint. Took me about 30 seconds.

    Would be nice if you could do the same.
