Todorovic’s Dartboard Illusion


After seeing this grayish dartboard below, and being a regular fan of Might Optical Illusions blog, the question arises almost spontaneously – Do the light and dark regions, as indicated by the arrows, appear to be different? Which region is actually darker? Believe it or not, they are identical! Errrm…Well, at least they should be! Please bear in mind that the picture you see below was first scanned and then uploaded by the person who sent it to me, so they might not actually be the same. Still, in the end it might help the illusion to work even better! As it might turn out that the darker region is the one that appears lighter at the first glance! You be the judge…

    They are too different!

  • Zanowolf

    Vurdlak – no mention that the whole thing looks conical, with the center being “pointy?”

    Love your site – keep up the great work!

  • Larry

    Me thinks we are getting our proverbial legs pulled on this one. I have attempted to block the sections off on my monitor with sections of paper and they still don’t look similar in density. hmmmm…

    Maybe I will attempot to load the picture into a graphics editor and do samples? Who has time over the next 48?

    • James

      Yeah, just put them into PS, and they’re the same shade of grey when you isolate the area they’re pointing to. Pretty impressive illusion.

    • Kermit

      yep.just checked it in photoshop.
      tis the same color indeed :)
      i didnt doubt vurdlak.
      its crazy how our minds trick us.
      but they are the same shad

  • Larry

    So I couldn’t wait any longer and did the cut’n paste exercise!


    If I could post the result I would but it seems to only be possible to post URLs here.

  • Larry

    I printed the image and it becomes more obvious to see the shading similarities and not so unreal.

    To all the people with messed up eyesight too!

  • holy shit-aki mushrooms!!

  • The Fozz

    They are not identical.

    Checked with photoshop and the identical coloured parts are the white on on the apparent darker region and black on the apparent lighter region which is due to their surrounding colours.

  • Kimon

    They looked the same to me when I covered the neighbouring rings with my fingers.

  • Bigbandsinger

    I copied the image to Paint and cut out sections to compare. They are close enough to be deemed identical. Sure doesn’t look like it until you lay one on top of the other. Good one V!

  • JLan

    Loaded into Photoshop and the are the same, (or extremely close).

    This illusion makes them look much more different than they actually are.

  • eee efff geee


  • me123987645

    They are very close in color but not quite the same (that is the dark grey in the lighter area and the light grey in the dark area).

  • Christopher

    I cut out 2 sample blocks from each band and placed them side-by-side in my Corel Photo-Paint. The ‘light’ band is in fact slightly darker than the ‘dark’ band!

  • Huh?

    “Me thinks”? What are you, a caveman?

  • Danielle

    Looks like Captain America’s shield!

  • Chakolate

    I didn’t believe it either, but when I used the Snipping Tool and moved one closer to the other, they do look the same.

    Nice job!

  • Sammi

    Tested in photoshop. They are the same.

  • magpiez

    Youve lost me, what do you mean?

  • The areas in question are the dark areas of the lighter rings and the lighter area of the darker rings. Look at the exact spot the arrows point at, not the entire ring.

    In short, while you may perceive the lighted area of the dark ring to be lighter than the shadowed are of the light ring, the gray density is the same in the darkest areas of the light rings as it is in the lightest area of the dark rings.

  • Doax

    Captain America shield ??? LOL xD

  • Phaeton99

    Far from identical, as a Photoshop sampling test proved. I suspect this is a result of artifacts from the data compression in the jpeg. If this were a vector image or high-rez raster with clean gradients, they probably would be the same values.

  • RitaSiminu


  • Tim

    The colours are identical. I used a drawing program to compare the two areas. Awesome illusion.

  • nyge

    they are the same tone. i made layers in photoshop and cut out one of the parts indicated with an arrow

  • tito

    both arrows are the same color, because it place on top, it does not matter the color of the target, the arrows still be black

  • Moustache1020

    It looks like its a photo of a conical object and the differences in color are produced by the angle of the surface the light is reflecting off of.

  • rich

    Tested in Fireworks, not crappy Photoshop. The apparent lighter area is actually darker.

  • Ericka

    The arrow on the left should be pointing to the band below. The illusion is in the way the light is shining on the conical shape for that same ribbon to which the right arrow is pointing.
