![MURDER DRONES Series Finale [TRAILER]](http://i.ytimg.com/vi/p6mhC5Iatns/mqdefault.jpg)
it was coloured for like 1 or 2 seconds then it went to black and white . 4 me
Because you moved your focus
+jmbuku19 that is also normal :) this is like the spinning wheel, where you focus on the center for a while and when you look away, the whole world seems to be spinning too :)
+jmbuku19 Yeah, it went away when I blinked O.o
+TheRobstargames I didn't and the colour still only remained very briefly.
+jmbuku19 You need to keep staring at the center where the dot was. If you move your focus, it'll revert back to black and white. But, if you look back at the center after looking away briefly, it should look colorful again.
Even though it was one for like a split second it was awesome!
Science!
+VladTeeVee Trick your brain and try and do the dare on the 13Horror com website.
+VladTeeVee I saw the color for about 5 seconds.
+VladTeeVee I saw it for longer cause I kept my eyes focused on where the dot was longer. Try it if you wish.
+FireWolfRBLX it was there until the picture went off screen you have to. Keep staring
I can't be the only one waiting for a jump scare to pop up.
This is RUclips after all...
+Probably Jack
It's official BBC videos. It can't goes wrong.
garfieldandfriends1 You'd like to think that.
+Probably Jack or Rick Astley
+Probably Jack Trick your brain and try and do the dare on the 13Horror com website.
i was thinking that too
shes wearing that god awful black and blue dress
+Courtney Cat haha
you mean that white and gold dress, you're welcome.
+Fred-o-saurus if you say so bud :)
+Courtney Cat You've gone and re-started world war 3
@@gosucalime no, world war 3 was when people argued whether pineapples belong on pizza
This video would have been way cooler if you just showed the picture the whole time and stopped showing us the women looking at the picture
just press pause
But then when he unpaused it would be lady head.
So this is what you need to do when watching 60s Doctor Who!
...with a few complications.
+William Tiley Yes. First get someone to add in the exact opposite colours, then stare at each frame for about 10 seconds, swapping to the b&w frame each time. Should work great!
+SouthpawCostumes lol
SouthpawCostumes Excellent!
+SouthpawCostumes LMAOO yeah hahahahah :D
FANTASTIC!
Same thing happens when you stare at a red piece of paper for 30 seconds and then stare at a white wall you will see a green piece of paper projected on the wall. It is a function of your brain to search for complimentary colours (colours opposite each other on a simple 6 tone colour wheel) and if they are not there our brain creates them for us. Your brain automatically feels more comfortable seeing red apples in green trees. and the colours purple and yellow, and the colours blue and orange. Colour psychology is so interesting.
The example in the picture may be a diferent mechanism. But the look into pickture for long enough and it can se its inverse in a wall it as to do with the cell in the back of the eye getting tired of "holding" that position, each individual cell/pixel strugles to swtich to another color for a set time.
*turns down volume and checks the ending just in case*
This channel is jot one of those channels. It's literally BBC.
Pause the video then alternate between the keys 5 and 6 on the keyboard, looks much better
+topsui pretty sick
+topsui Awesome discover!
the fact that you found this out baffles me
+topsui just keep pressing 8 and you'll see an even better coloured picture.
+topsui 5 and 8 works better.
Pretty nice demonstration of how our perception of reality is tenuous at best.
It worked the first time. I then tried it over and over as I was skeptical and because I wasn't letting the light in, I saw it as black and white all the time. When I did concentrate on the dot throughout once again, when you move your eyes away from where the blue dot was, it goes black and white, and if you move back to the centre (where the blue dot would have been) you see the colour again (if you do it in the 2 or 3 second window you have before it is seen for what it really is).
Simply astounding!
Fun fact: it also works when using just one eye! I closed my left eye while staring at the center dot, then when the black and white image popped up, it looked as if it were in colour. I closed my right eye and opened my left eye: black and white image. I closed my left eye again and opened my right eye again: still colour! And so on. The effect remained for about 3-4 seconds. Try it yourself!
Omg thats even more crazy
Imagine being an adult and having 666 in your handle.
I choose to remain childish.
Ok! Ok!
This is just a simple mechanism called Opponent- Process Theory developed in the 1870s, it is the idea of perceiving colour in terms of paired opposites such as red with green, and yellow with blue. A possible mechanism for the theory is that bipolar cells are excited by one set of wavelengths and inhibited by other. Which are attached to the cone retinal receptors. But this theory has the limitations of color constancy & retinex theory.
+HanbinGo Very Insightful knowledge, it is a fascinating mechanism.
ironic how she's wearing the black and blue/ gold and white dress
0:51 saw it in color without staring at the dot B-)
Eye is being temporarily "wearing out" the colour receptor. When true b&w pic appears, you see the opposite colour. Grass in odd colour pic purple so it then becomes green ( the opposite colour.
This is just about "eye delay". It shows the optical phenomenon that focusing on an image long enough will make it "stick to your retina" for a few seconds.
Like the experiments where you focus on a Spiral for 1 minute and then you'll se a spiral as an overlay on the next image you see.
It's the same thing here - staring at colors makes them appear as an overlay on the next image you see, for about 2 seconds.
0:04 she's wearing the blue and black/ white and gold dress
Now i have a subliminal impulse planted in me, I have an urge to visit old castles.
so cool!
Well done
and this is one of the reason why I love science so much T-T
Witchcraft!
Timelord
+The Madhouse Which craft ?
Proxy, The Hornet POX
I was thinking neuromancy.
for it to worked longer don't look away or blink your eye. this is so cool.
Its a neat trick, its just taking what happens to your eye with when you're in a room of light and you close your eyes in darkness and you see the images still in your eye but as a 'negative'. Nice.
Had to go back and pause just after the dot, just to make sure it wasn't just the video. Good illusion!
0:05 I like her white and gold dress!
This is so cool!
You have to keep staring at the one spot to keep seeing it in colour, you can look somewhere else and it will be b&w and then look back to the central dot and you'll see colour again
That's pretty cool, I also tried not looking at the dot and it stayed black and white. I was making sure that it wasn't and edit.
When it went to black and white I saw Michael Douglas............ anyone else?
+MarkMash17 Nope, i saw Michael jackson
+MarkMash17 I saw Martin Sheen pretending to be Michael Douglas. wtf man?
I saw Moochelle.
it lasted for 7 seconds then i only saw the middle in color
It's cool because each time you blink it gets a bit more black and white
So cool!
that is Nice........................................!
Woah, this actually worked for me. Pretty cool!
shit it actually worked !
ikr is worked
that... WAS AWESOME
Nice. Video of the day!
Guess the internet has traumatized me, I was bracing for a screaming horror face.
I saw a little bit of green when looking at the dot. It does work
Omg that was insane!!! So trippy
try it with one eye open and one closed. you see both and can change from color to B&W. very neat stuff
By staring at the colour dot and false colour certain colour receptors in your eyes fatigue, then when the B+W image appears you get what's known as an after-image...appears as normal colour, this will naturally fade over time as your colour receptors recover...and image is seen again as B+W

Oh my this was incredible!!!
This happens, quite literally, all the time for me; I only need to look at a color for a very short time (less than a second) and then look at a white area to see the inverted color for a while. I'm 22 and it's always been that way for me. I haven't seen anyone saying it works that way for them as well, most people seem really fascinated by this video or it doesn't work for them, but throwing the question out there: anyone familiar? And does anyone have an explanation?
I know it's late... But I've just tried and it happens to me!!! Look for "Afterimage" in Wikipedia. I think that explains this.
They simply uses natural adaptation of eye receptors to bright colours. They just "turned off" appropriate receptor off by corresponding bright colour. For example bright purple colour will turn off "red" and "blue" receptors, but "green" will be still on and you will see green grass :)
Loved this so cool
I find it absolutely fascinating that this didn't work for me at all.

So?
Awesome!
That actually shocked me for a sec because it was in full colour.
Just the grass looked green to me for like a second and then went back to black and white.
THAT WAS TOTALLY WIKED!!!
Everyone talking about the image but nobody noticed how this woman's black and blue dress miraculously turned to white and gold in between shots! :o
i've never been able to get such effects to work
This video simply depicts the test subject's results with a brief example for us viewers to try. Pause and stare at the colour image for 30 seconds or a full minute for a better prolonged effect rather than the quick couple of seconds most have have been reporting.
This effect is nothing new and there are many optical games that do the same however you've probably found those most commonly with reverse hard contrast black and white illustrations. When we stare at a reverse "negative" for a prolonged time it burns the image into our retinas and then when we look at a neutral plane we will see the reverse of that negative, hence the positive. This is really the same where the colour image we were shown is a negative of the coloured photo.
I keep looking in the middle where the for was when it changed so it stayed colorful xD
I thought it was a joke at first, because I immediately saw it in color, I rewind it a couple times and it slowly turned to black and white.
Oh wow. That just worked on me. That's amazing.
That was awesome
Amazing!
If you hold the stare and be focused, it lasts for a few more seconds. That's a great video !
I find it remarkable there are human eye receptors in the camera they are using.
She's so impressed, how has she never seen this before?
About a quarter of a second it was in colour then immediately reverted to black and white.
If you focus on the center, don't move your eyes, and not blink.
The image will remain in full color for you to see, and you can even inspect it through your peripherals.
The grass on that little cliff is a distinct yellow whereas the rest of the grass is a deep green, the water on the right is a dark blue, most of the people seem to be wearing white and the castle is a dirty grey/beige. And the sky is a hazy grey with a tint of light blue.
Seriously. Try it yourself.
👍👍👍👍 i tryd not lookn & lookn it works 😂😂😂 the longer u stare the longer the color
Freaking awesome :D
False, we constructed a full color image not from a black and white image but instead from an invert of the original full color image. It's a cool optical illusion but the description of the video makes it seem like our brains are taking a black and white photo and making color from it which instead, our brain is making color from the invert.
+Patrick Bandy I agree. It makes you think that they are colouring a black and white image alone. It doesn't say it involves an image that is already coloured
THE BLUE AND BLACK DRESS!!!
wow! thats amazing!
its fascinating to see that my brain thought that the yellow flowers were red.
I didn't notice the people in the black and white one, wow.
I really don't know why this is suddenly trending on facebook.
This is nothing new.
I only saw it for an instant but that was amazing
doesnt it change for everyone at .50 secs and end at 1.00 without staring at the dot. Try showing to anyone but start at .46 sec. or close your eyes and ask someone else to tell you when its exactly at .50 secs and photograph it. Do it anyway you can think to test it. It will be in colour at .50 even if you dont look at it. Either I will feel silly if im wrong or everyone else commenting will.
Actually worked. nice
Awesome!
This afterimage effect is well-known in the psychology of perception. Nothing new or startling here.
how could I reproduce this on old airplanes photos (to find the real colors for peanuts scale)???
She's wearing that White and gold/Blue and Black dress
Omg! At 0:05 look at her clothes! Its the BLACK AND BLUE AND WHITE AND GOLD.
amazing
like the fact that she's wearing the white and gold dress.
When it changed over I though 'What's supposed to happen? You have just put up a coloured image...'
The first time I tried it it was only in colour for a second but then I realised I needed to keep my eyes fixed and did it again. Mind blown.
Wish I could do this with the black and white photos of my parents so I can see my parents as kids in the photo
brains are amazing
If you blink, these receptors will reset and it'll turn the picture grey again, if you dont it stays colored a while longer
Whoooooaaaaa!
That's pretty cool!
My brain has installed Photoshop!!! I didn't know before until this video 😁 lol
aww but what i want to look around. still a neat trick though
Only saw the grass turn green, everything else was still black and white for me.
It finally worked for me around 0:50
Personally for me, the only difference that occurred was that the grass turned into a faint green and then faded completely back into black and white.
*flips desk*
Hey 0:05 She's wearing the white and gold dress!!!
THAT was magical. @-@
Correct me if I'm wrong, but she said its our brain that is doing this, which I think is false. Its more physiological than that and i think that this happens because the negative colour image desensitises our eye to those colours, so when we see the white light of the grayscale we only see the colour that is negative to the negative colour image.
Do not move your eyes to other location after the photo has just changed, you should be able to see the coloured photo as long as you keep your eye contact fixed to the spot. I get at least 8 second before the picture slowly turn back to B/W.
