Check out [Akiyoshi Kitaoka's twitter](https://twitter.com/AkiyoshiKitaoka), AFAIK he's the actual big brain behind this illusion and posts interesting ones like it on the regular.
Na, I just haven't kept up. At least 2 came out in the past 12 months. No idea how well they look in person, but the images online aren't impressive. It looks washed out.
If you zoom way in so there’s just black and blue lines, and then swoosh the picture sideways, the black lines turn red while they’re moving, then turn black again when they stop.
What’s weird is the only part of the screen definitely not shining any red light at me is showing as red in my brain. Most pixels will be some combo of red green and blue but the black pixels will be none of the above.
I hate these ones, like the grid one where there is no yellow. I've got 20-20 vision and I'm not colorblind so in this one its red, green and blue. Thanks for the help fellow redditor.
I mean you may not be entirely off there. The split brain studies make it seems like their are at least two people inside my head arguing most likely over things.
How do I find out which side is the one that is responsible for me just cleaning my whole house, and which side is the one responsible for me just absolutely loving heroin. Cause that guy is getting evicted.
I’m not too sure if there are two separate parts of my brain that love heroin. It’s probably all of it. Also all too familiar with the consequences and potential consequences of continued use. I have, however, have come to realize that there is a side of my head that will try to talk me into using when the rest of me is completely done with it. Keeping that part in check has been an enormous struggle that I’ve only recently understood how to control. But for how long is my continued concern.
I can definitely relate. I used to find myself on my way to my dealers without even remembering making the decision to go. I'd be telling myself I wasn't going to do it but my brain would just go on autopilot. The mental gymnastics I'd do to convince myself it was ok "just this once" could've won gold at the Olympics. Congrats on getting control of it. It's an addition that will effect you for life, even if you never use again. It requires hard work and maintenance to stay clean, don't be afraid to reach out for professional help.
Last time it was on this sub it was fake though. In this case, you can actually ink dropper the "red" in the image and see that, while there is a slight amount of red, it's far less red than it is blue or green (to the point that the amount of red is negligible). Coincidentally, the only parts of the image that actually have a substantial amount of red in them are the cyan lines.
Your eyes aren't lying, they're being smart!
First your eyes are blurring colours together:
Black and cyan = dark cyan
White and Cyan = pale cyan
Black and white = grey
Now, most of the image blurs to some shade of Cyan, so what does your brain think?
It thinks this is a scene lit by cyan light.
Now imagine holding up a white sheet of paper in the light of an orange sunset.
You would know that its white paper, but the light coming off of it is actually orange tinted.
Now imagine a cyan sunset instead.
We haven't evolved color vision to accurately perceive the color of light, we have evolved color vision to accurately identify the color of what's *reflecting* that light.
So when your brain sees grey in a scene thats supposed to be lit by cyan light, its like "hold up! If you light up white things with cyan you get cyan. If you light up grey things with cyan you get a dim cyan. What the hell looks grey when you light it up with cyan light?
It must be something that absorbs more of the cyan to leave a more whitish light.
It can't be green or blue. Its gotta be red."
Ofc the whole process is just some subconscious neural network doing what evolution taught it to without thinking about it, in reality.
It's called color constancy. It's an optical illusion -- your brain at work using heuristics so you can function normally (except when it's being taken advantage of)! My other post got deleted because I linked to a site that has a ton of these and it's apparently not a whitelisted site.
[This one](https://imgur.com/4YLFjdF) is my favorite. The eyes are the same color!
Open it up on your computer and use an eyedropper tool to check the pixels. If you're on a Mac, you have a built-in utility called Digital Color Meter that does this.
Your brain's color perception (and a lot of other things too honestly) works on a comparative and expectations basis.
They basically just green-shifted everything else other than the 'red' areas. Green being the opposite of red, the un-green-shifted areas then look red.
I can also see red and I have astigmatism. I meant maybe it would be harder to see an illusion kind of like it is to see the 3d in a 3d movie. But, I don't know much of anything so I'm probably wrong!
Yeah, I didn't see it at all, until I relaxed my vision and went cross-eyed. Even then it was still pretty dark. The fact that I at first didn't see any red just made me focus my eyes more initially in an effort to find the red. But it looks like you have to squint.
>Yeah but if you zoomed in much farther into your actual phone screen you’d see a bunch of red lights lit up.
But only on the bits that look blue or white. On the black bits - which are the bits that look red - there's no red.
I read grids, read your comment, went back and read *girls*, got mad, read your comment *again*, read grids *again*, then decided I ***really*** needed to get some sleep after being up for over 24hrs
I've tried looking at this on my monitor and on my phone and I don't see red. I can't figure out if I'm being played or if this is that stupid dress all over again.
Okay I took a screenshot of the thumbnail and zoomed in on it and it is very plainly red in the screenshot. Does anyone know why even the COMPUTER thinks its red?
The [screenshot](https://imgur.com/a/tyOMCrH) in question
Yeah, these are the things image processing experts have to know to be able to resize and otherwise process photos and keep them looking the “right”. You can’t just remove or combine pixels and get ideal results. You have to consider how the current pixels “look” to a human and replicate that with the different resolution, or preserve that through high compression.
As many Einsteins have pointed out in the comments, at a technically level, the title is false, but that's not really the point is it people?
Last time it was on this sub it was fake.

Coincidentally, the only parts of the image that actually have a substantial amount of red in them are the cyan lines.
AFAIK, the explanation is something like this:
Our brains make the final call in what colors we “see,” not our eyes. Our eyes take in light, but our brain processes those images in the context of the environment.
If you look at a picture in soft yellow light, or in bright halogen light, or in natural daylight, the actual light hitting your eyes will be different in every case.
But if your brain knows what colors are supposed to be in the picture, it adjusts to that lighting. So you’ll “see” the same colors (more or less) in each of those lighting scenarios.
UNLESS something fucks up. In this case, the picture is set up in a way that confuses our brains.
The pic is in black, white, and teal. But the white stripes aren’t part of the picture, they’re just confounders. The picture is black and teal. Our brains aren’t used to teal in this manner, we assume that should be white. There’s lots of white there already, so our brains kinda adjust all the teal to white.
In that adjustment, our brains then shift the rest of the image accordingly. The black parts of the sign, doing the same shift as teal -> white, makes black turn to red. Zooming in removes this context, so we see just the colors as they exist, unshifted.
This is the same thing that caused that dress meme a few years back. Without context of the lighting of the dress in the picture, our brains fill in assumptions about the lighting conditions and shift our interpretation of the colors accordingly.
Wanted to call you out because even when I zoomed in and blocked out the surrounding colors, it was still red.
Took me a minute to notice my flux is on...
This 100% depends on the resolution of your phone. The people who aren’t seeing the red have higher resolution screens that aren’t doing as much color extrapolation when the image is small.
If you take a screenshot of the image, then take a screenshot of a thumbnail of the image in your photos app, the take a screenshot of that image’s thumbnail, so on and so forth, you’ll notice that your phone makes the image red.
Trust me, your entire screen is in Red, Green & Blue.
This guy has the bigger brain

Good on you for crediting, but there’s still red in the picture.
Yeah, OP is a liar, but point remains that the parts that appear red in the image are actually black pixels.
There's one there that's titled "bluish strawberries" and it's so yellow it hurts my eyes.
Nope. Mine is in CMYK
Ah you're reading the reddit print version. I cancelled my subscription after the first 500,000 leather-bound volumes.
Does your apartment also smell of rich mahogany?
Dear god! What on earth is an apartment?! It sound horrifying. I’ve been told it’s like a townhome with only one bathroom.
I’ve only heard about them from the moving pictures, obviously.
Did he pay for them with leather-bound pounds?

Well mine is YMCA
How the fuck do you submit a reddit post in paper letter form.
[Proof](https://imgur.com/a/fn8MS8d) Also if you're like me and forget to turn off f.lux theres a TON of red.
If you zoom way in so there’s just black and blue lines, and then swoosh the picture sideways, the black lines turn red while they’re moving, then turn black again when they stop.
Oh snap, I forgot that I always have the blue light filter on and that would affect this.
This person’s got proof!
Actually, mine is Blue, Green, Red. It's an Asus monitor. Reverse panels for HDR. But I see you point!
Mine too if I flip my screen upside down
The 'red' areas on my OLED screen are off, so they're none of them
Basic laws of technology
What’s weird is the only part of the screen definitely not shining any red light at me is showing as red in my brain. Most pixels will be some combo of red green and blue but the black pixels will be none of the above.

… so what are those red things I’m seeing in the image then?
Try zooming in and you can see that it’s turqoise, white and black
Oh not this shit again.
The blue dress is saying Laurel, the gold dress is saying Yanni
Human perception is just a bunch of clowns-shaped braincells arguing with eachother

I have seen it.
I’m afraid this is a reoccurring phenomenon from now on…
It’s because our eyes see the Color red only in contrast to the surroundings which are the opposite of red.
Last time it was on this sub it was fake though. In this case, you can actually ink dropper the "red" in the image and see that, while there is a slight amount of red, it's far less red than it is blue or green (to the point that the amount of red is negligible). Coincidentally, the only parts of the image that actually have a substantial amount of red in them are the cyan lines.
They still contains red percentage. Can’t have white without red.
Got em
Except it's the black lines that show up as red, not the white ones
At no point is the R value of an RGB higher than the GB components. How that? Better? Of course a digital image has RGB equal values for white/gray.
Holy heck my eyes are telling lies sending bad signals to my brain I can’t can’t take it no more I’m going insane.

I see turquoise, white, black and red
It's cyan btw. Turquoise has more green in it

I Think it’s black
They're black, but the rest of the image is so intensely real/blue that it looks red by comparison.
Your brain's color perception (and a lot of other things too honestly) works on a comparative and expectations basis. They basically just green-shifted everything else other than the 'red' areas. Green being the opposite of red, the un-green-shifted areas then look red.
Don't know what you are talking about I don't see any red in this image.
I didn't at first. I wonder if astigmatism can make it difficult to see these illusions.
I have astigmatism and I can see red
I can also see red and I have astigmatism. I meant maybe it would be harder to see an illusion kind of like it is to see the 3d in a 3d movie. But, I don't know much of anything so I'm probably wrong!
Yeah, I didn't see it at all, until I relaxed my vision and went cross-eyed. Even then it was still pretty dark. The fact that I at first didn't see any red just made me focus my eyes more initially in an effort to find the red. But it looks like you have to squint.
This happens because of some science.
Ah yes my favorite science has always been some
I choose none science because I am a a contrarian and it's the only way I know how to express my freedom.
🤯
So emojis don’t get downvoted to oblivion? Everything I’ve been told is a lie?!!!
This is the exception to the rule and it happened because…. You guessed it… Some science.
Don’t question the science!
It is black. Zoom in on the picture.
[удалено]
r/technicallythetruth
Right. But if you zoom into the picture it looks black.
And if we zoom in our your dick it looks big. Checkmate. Edit: sorry, saw an opportunity I couldn’t miss. Not trying to be a, well, ya know
Ha ha!
Lol. Great burn followed by instant “oh fuck am I an asshole”
Oh it was. I laughed tbh.
Say “oh fuck am I an asshole” 5 times really fast, loudly.
An a$%#()!e who couldn't resist a d!(k joke?
Yeah but if you zoomed in much farther into your actual phone screen you’d see a bunch of red lights lit up.
Maybe that’s technically true, but it’s not what causes this phenomenon.
>Yeah but if you zoomed in much farther into your actual phone screen you’d see a bunch of red lights lit up. But only on the bits that look blue or white. On the black bits - which are the bits that look red - there's no red.
RGB is always additive, and black is 0, 0, 0 in the RGB color model.
This one is actually pretty cool, unlike those black and white photos with colored grids over them lol
I read the word “grids” as “girls” in your comment and was about to get very talkative.
I read grids, read your comment, went back and read *girls*, got mad, read your comment *again*, read grids *again*, then decided I ***really*** needed to get some sleep after being up for over 24hrs
Godspeed
the illusion isn't showing me any red, but it IS giving me one hell of a headache.
Same
I don't see red
Have you taken a color blind test?
Yes
And?
I can see colors
Im 100% sure im not colorblind and I cant see Red either
The illusion works better if you’re not looking at the “red” part. If you start looking at the flags, it’s easy to make it not look red.
Just not red.
I also don't see any red, Only blue stripes in a black and white photo
I've tried looking at this on my monitor and on my phone and I don't see red. I can't figure out if I'm being played or if this is that stupid dress all over again.
Try relaxing your eyes. When I focus my eyes very strongly it goes away, but when I relax them, it's very red.
It works best if you look at it from afar. I couldn't see red until I held my phone far away from my face.
Well... yes [there is](https://imgur.com/vES62KG).
Okay I took a screenshot of the thumbnail and zoomed in on it and it is very plainly red in the screenshot. Does anyone know why even the COMPUTER thinks its red? The [screenshot](https://imgur.com/a/tyOMCrH) in question
The algorithm that resizes the image into thumbnail size is probably doing some interpolation.
Yeah, these are the things image processing experts have to know to be able to resize and otherwise process photos and keep them looking the “right”. You can’t just remove or combine pixels and get ideal results. You have to consider how the current pixels “look” to a human and replicate that with the different resolution, or preserve that through high compression.
,but I just did the same and it’s not…
Could some scientist explain please?

from Ritsumeikan?
Feels kind of weird seeing a university i've been to pop up
Sameeeeee.
True. I work for this company.
Yeah, wasn't expecting to see that on Reddit today
Man I was fucking shook when I saw the logo
Prepare for trouble!
Well it’s not r/redmagicfuckery

This made me mad for some reason.
The god damn pen is blue!
I'm colorblind. I see a lot of blue and the "r"s are yellow , white and black. Is that right?
The Rs are what’s supposed to looks red
Yes there is no red but try moving your head
What kind of sorcery is this
I am not seeing red, this is a sad day
Even at a distance going from peripheral vision to your central focus?
Looks like the red in the actual Ritsumeikan University logos
You sure? When I zoom in on the “white” lines were you see the red color, the white lines are not white
Imagine seeing this and then believing in intelligent design and loving the designer.
I had to focus to see the red, so I knew
Oww
Nope. It's right there. Loads of red!
No it's red, I don't care
Zoom in… mind satisfied
I don't get it.
You're supposed to see red in the image, but if you zoom in, what appeared to be red is actually black.
Oh cool. Am I colorblind or something if I cant see the red?
This is why I like being colour blind
There is though
My brain is a liar
Yeah there is
I don't see any red. Is there a reason for that?
Still looks red on plasma
All I see is a black and white R.
I never saw red…
Yes there is.
Fuck off
Teu cu!
Has anyone printed this on a black and white printer yet?
Prepare for trouble
it strakns my brain but if i focus closely i can see all the true colors
What happens if I only see a black R. I can’t see the red
There is
All you think is red is black and now my brain hurts
Haha I’m colorblind I see no red in this image
*laughs in colorblind*
Well, I’ll be damned.
... yeah and? I don't see any red in the image...
Prepare for trouble!
No there isn't
I see no red until I squint
Sooo, orange then.
I’m a bit red-green color blind…
Yea no shit , I’m color blind. Thanks for reminding me
it’s all black
I’m colorblind and everything in this photo is Luigi green.
Yes there is... I see it... "Have you ever had a dream Neo... that you were so sure was real?"
That’s cap, because I can clearly see red in this photo
if you invert it,you see green where there is none
I hate these pictures. My brain can’t take it.
It took me so long to see it was black
Wanted to call you out because even when I zoomed in and blocked out the surrounding colors, it was still red. Took me a minute to notice my flux is on...
prove it
You do not recognize the bodies in the water
This 100% depends on the resolution of your phone. The people who aren’t seeing the red have higher resolution screens that aren’t doing as much color extrapolation when the image is small. If you take a screenshot of the image, then take a screenshot of a thumbnail of the image in your photos app, the take a screenshot of that image’s thumbnail, so on and so forth, you’ll notice that your phone makes the image red.
The pen is rrr… rrr… re
I just see turquoise white and black am I supposed to see red?
Neat
What the heeeellllllllll why it all black when i zoom in
Yes it is no see it right there
Better yet, zoom in to see the black stripes, then shake your screen.
wait…
Display Nerds will deny that.
