See a new color you’ve never seen before!!…Well… at least never before on your monitor. It’s a startling example of how poor the green/cyan element is on TVs and monitors generally. The colour you are about to witness is actually true Cyan … a colour that is heavily diluted on the vast optical illusions 10 majority of monitors (thanks to colour pollution). It’s a pity one needs an optical illusion to demonstrate this, but at least you can see what you’ve been missing ;-) Anyway on with the illusion….

Stare at the white dot in the centre of the red circle. The longer – the better (two minutes and you’ll get a much stronger effect). Always try to keep focused on the white dot. It’ll be worth it.
Soon after staring, you’ll start to see a thin rim of light around the edge. Don’t stop staring though yet! Wait another minute – keeping your head perfectly still.

Once you’ve done this, slowly – move your head backwards – making sure to keep your eyes focused on the dot at all times. The circle’s rim will glow brilliantly with true Cyan! Keep on moving your head slowly backwards, and it’ll glow very hot!…

The blue/cyan colour chart to the right isn’t part of the illusion, but there to demonstrate that the ultra cyan you have just seen is not in the monitor’s color palette! It should be, but isn’t.
It’s an amazing effect.

  37. nobody special says:

    It is too on the color pallete…. trust me…. I can hear things people can’t hear, and see things that otherwize can’t be seen… usually high pitched noises and colors. I have an eye for matching colors. Don’t mean to sound like a know-it-all but it’s true. There can’t possibly be a color that’s not on the color pallete. The colors off to the side are different shades… and each one is gradient by one on the slide. The color you see is near the center of the pallete. you can see this if you stare long enough, then look over at the pallete at a distance so the blue circle is just outside of it.. you will see its matching color.

  38. Lindsay says:

    CKOEOWL aka cool get c o o l and k e w l any way that thing is so awesome

  43. M 2 the H O says:

    that was way kewl.
    but nobody special, srry but ur wrong 2,
    cyan is on the colour pallet but not on the 1 bside the red dot.
    that pallet is blue shades,
    not cyan shades.
    and personally i think that u only see weird colours cause u have bad eyesite,
    any1 cud see its not on that pallet,
    theyre pure blues fcs!!!

  44. summit says:

    the circle can also represent the “center” of your vision… you have on focal point of your vision, and the circle can show it, when you get close enough to the screen… truly is a beautiful color though…

  45. alq says:

    that was really cool. i could still see the color for a while after i stopped staring

    Cyan is in that on that chart. Bottom left hand corner.

    There however is a large difference between computer cyan and print cyan.

    I honestly don’t know what you think you’re seeing, but displays have always sucked for true colour accuracy.

  78. claudia says:

    oh my god dat is amazing the circle looks so real its hard to believe its not real nd only imaginary its really cool on the palm of ure hand nd if u look at someting pink it turns purple its really freaky

    This isn’t really an illusion, it’s to do with complementary colours. The chart is of some shades, but probably not the complementary colour of that particular red. Nice cyan though. Awesuuuum…

    My retinas are totally branded with the blue circle! The further away I moved my head, the bigger the cyan colored circle got until it started going out into the white part outside of the rectangle! It’s evil that that color doesn’t exist on screens… now when I look at my hand, it’s all blueish, and the further away my eyes are from my hand, the more blue area on it! It looked like a blue light on my hand…

    what you can do too, is watch the image for 2 minutes liek in the instructions, then close your eyes and keep your hand before your eyes so your eyes don’t catch any light. Then, even when your eyes are closed, you can see the cyan. But this effect is a bit too strong. I see it even now while typing this comment :)

      It also took me just 20 seconds to see it,
      1 thing some of you could miss is that all the blue spots on the pc and besides it turn gray.
      It’s like the cyan circle steels the blue and converts it in tu cyan brightness

    Absolutely breathtaking.

  215. Blue says:

    Ooooooh it’s so pretty :)

  216. Robin says:

    How to delete the circle? Turning of my monitor doesn’t work ;)

    • Someone says:

      The circle is an optical illusion that stays in our eyes for a small amount of time after we have stared at something for too long.

  217. alice says:

    whenever i look at something white, i now see a blue circle!

  218. fossda says:

    my computer is capable of producing WAY more colours than that.

  219. chey says:

    COOL, also the after effect is a blue dot same size as red and the red dot starts to get grainish after starting for 60 sec or so . . .

  220. samarrian says:

    haha i was totally cool

  221. FlossBoss says:

    The red circle illuminated a blue circle. I followed it around on the screen for like 3 minutes and it’s still there! I’m not sure if that’s bad or not XD

  222. October says:

    I think I stared to long, there is a blue circle everywhere I look.

  223. tarzan says:

    AWESOME ! ! ! ! ! ! ! ! ! ! ! ! ! !!

  224. FINALLY says:


    BTW if you wanna remove the effect , try closing your eyes for 5 to 10 minutes. ((But it should automatically disappear after 2 to 3 min of ooking to any other thing))

  225. johnny_depp_fan says:

    Um . . . okay . . . moving along.

  226. Someone says:

    Now if your eyes are getting reeeeeally sore, at about 1 minute just stare at something white. Like the Jesus face illusion.
    It also makes it easier to compare to the color chart, and lasts a lot longer (like staring at something really bright then closing your eyes)
    I had to change the amount of time my computer went on standby for.

  227. TheRhyslightning says:

  228. Someone says:

  229. Someone says:

    I see the cyan color after about half a minute, and it gently reverberates for about another half minute.

  231. Bluestar says:

    Is it possible that one day we will discover a new color?…

    What are logical ways to create optical illusions?…
