Stewat, it is how your brain interprets it. How do you think your eyes see things? Without the brain?

I love the colors green and blue together, but this illusion is awesome... i get it now, and in my pic., im not that old I'm much older now, that's from when I was around 5 years old. I'm actually not a science person, so excuse me!(or u!)

It's not "just the brain". The key is the thin orange and magenta spirals, which at first glance might appear to be one and the same. They are not and they greatly affect the perception of the broader spirals, as they're much thinner. At one level the eye/brain normalizes the colours within the broad spirals, but on another level the two contrasting colours exaggerate the difference.

After opening the illusion in Photoshop, try blurring it (Filter->Blur->Gaussian Blur->4 pixels) and see what happens.

Another helpful experiment enyailsto desaturating the illusion (Image->Mode->Grayscale), which reveals that the eye (or 'The Brain') still see some difference between the two spirals, while the grayscale value is of course the same. The grayscale value of the magenta and orange spirals are not.

EXACTLY THE SAME PROCESS AS A RGB TELEVISION. THE BRAIN UTILISES MINIMAL COLOURS WHEN THE COLOURS ARE IN TINY FRAGMENTS AND IT MIXES THEM INTO MULTI COLOURS. SAME WITH THIS ILLUSION. THE MIX OF COLOURS CREATES ANOTHER COLOUR.

Oh dear, my eyes ache trying to figure out before you explain further. I am not good at photoshop so I cannot experiment further with this but I am always up for a nice illusion. This is fascinating.

2009-07-03T07:58:55.600+10:00

This effect is solely in the brain. Photo-receptors in the eye act exactly like (inefficient) photo-receptors in a camera.

The brain is slow to process information from the eyes, so it takes shortcuts to give the appearance of higher speed, like motion-blur and mixing colors together. Most optical illusions result from these shortcuts, though some illusions, such as afterimages, result from the function of the eyes.

It's an illusion.

Deconstruct it by selecting areas of similar colour (easily done in Photoshop or Gimp). You can see that there are only three colours in the image - green, orange, and magenta.

If you take each of those colours and create a new layer of each individual colour and pattern you can enable and disable each layer to illustrate the illusion.

With only the green layer you only see green spirals. When you add the orange layer you see a subtle difference in colours. When you add the magenta background the blue and green are very obvious.

Most definitely is real. If you want to test and don't have a photoshop program...just use the eyedropper on the blue and then fill in some orange and purple lines with it...they match both the 'blue' and 'green'. Not even a need to check the RGB, pure simple proof, no change whatsoever.

I just clicked on the picture and zoomed in with my browser and it is obvious that the part that looks blue has a blue border and the part that looks green has a green border. So FALSE, this is NOT an illusion.

2009-06-30T11:57:14.605+10:00

An interesting thing to do is to cover up everything surrounding a section of the blue color with your fingers. The color shifts instantly to match the green. That was cool.

If you do open this in Photoshop and get out the dropper tool you will see that the colors are different. You can look in the info pallet and see that the numbers are not the same.

2009-06-30T05:16:39.771+10:00

Copy the picture and, in your favourite viewing software, zoom OUT (not in) until the individual lines are smaller than the pixels on your display. They still seem green and blue. What's that all about? I can easily tell they have the same RGB values otherwise.

2009-06-30T01:31:17.413+10:00

This is pretty cool. I disagree with Stewat claiming that this is a function of your eyes and not your brain. Your magazine analogy doesn't work because it's not as if we're seeing the purple and blue and interpreting it as one color; we can still differentiate very clearly between the two, hence it's not an issue of limited visibility (until you got very very tiny, then sure). I think the illusion is your brain just making relative judgments on colors, much like black and white illusions where it looks like two shades of grey are very different when they're the same.

Lastly, there are absolutely different terms for blue and green in Japanese for whoever was claiming otherwise, that's nonsense.

2009-06-29T21:29:25.334+10:00

Freesoul, this thin border of blue around the green is an illusion. zoom and measure (with the eyedropper set to 1 pixel and not having the picture re-rendered to prevent anti-aliasing by the software you use.)

2009-06-29T05:24:20.231+10:00

I'm not sure about you guys but like some else said earlier that the RGB on both the colors are diffrent....but close enough that and "normal" person wouldn't see the diffrence
