The dress debate: Is it white and gold, or blue and black? - A complete explanation.

Question: Is this dress white and gold, or blue and black?

How can two people look at a photograph of the same dress and see different colors?

Is this dress white and gold, or blue and black?

It all started when a Tumblr user named Swiked posted a picture of a dress on the Internet on Feb 25, 2015 and asked, "Guys please help me - is this dress white and gold, or blue and black? Me and my friends can't agree and we are freaking *** out." The internet nearly collapsed that night and the following day over the debate about the color of a dress. Many celebrities have tweeted their views. Millions of the commoners have joined in via Facebook and other forms of social media. The dress has been mentioned online more than 20 million times. The Ellen Show picked up on it, saying on Instagram that "From this day on, the world will be divided into two people: blue and black, or white and gold."


Answer: In reality, it is indisputably blue and black dress from a British company called Roman.

The original dress

What is going on?

Are dresses white and gold, or blue and black?

Original dress
Original dress

First of all, the dress image that we see on swiked.tumblr.com is the image in the middle. The dress color of this image is actually seen by most people as pale blue-dark gold and quite different from the original dress which is blue-black. Apparently, Swiked's friend, who took the picture, is no photographer and the image she took is over-exposed and the lighting conditions have something to do with this. You can use Photoshop to brighten up the image to make it white-gold as seen in the image on the left or darken it to regain original color as seen in the image on the right. And indeed, several demonstrations on Internet and Youtube have shown that by tilting your computer screen, thus changing the brightness of the screen, can change the perception of the dress's colors

Now, the second question: Why two people look at the same image in the middle and see different colors?

One group see the color as white-gold resembling the image on the left and another group see the color as blue-black resembling the image on the right. Why?

Scientific explanation

There are two types of photoreceptor cells in the retina. Cone cells are responsible for color vision as well as eye color sensitivity; they are less sensitive to light than the rod cells and function best in relatively bright light, as opposed to rod cells that work better in dim light. At very low light levels, visual experience is based solely on the rod signal. This explains why colors cannot be seen at low light levels.
Cones are normally one of the three types, each with different pigment, namely: S-cones, M-cones and L-cones. Each cone is therefore sensitive to visible wavelengths of light that correspond to short-wavelength, medium-wavelength and long-wavelength light. In layman's term, the cones cells are color sensitive, specifically to red, green and blue.
Because humans usually have three kinds of cones with different photopsins, which have different response curves and thus respond to variation in colour in different ways, we have trichromatic vision. The three pigments responsible for detecting light have been shown to vary in their exact chemical composition due to genetic variation; different individuals will have cones with different color sensitivity. This may explain why people perceive the dress color differently.



Why the same person may see the dress color differently at different times or why do two persons see it differently ?

Color afterimage
An interesting effect occurs when staring at a particular color for too long. Such action leads to an exhaustion of the cone cells that respond to that color - resulting in the afterimage. This vivid color aftereffect can last for a minute or more. For those who see the dress as blue-black, if you have looked at the dress for a long period of time or exposed to blue color somewhere else, the dress color may turn into white-gold.


Stare at the center of the blue circle for 60 seconds, and afterward switch your view to dress below. The dress color within the view will turn into white-gold. If you do this repeatedly, the whole dress may also change its color.
The dress color after-image


Conclusion

There are three types of cone cells in the retina and each contains photopsin specifically for red, green or blue color. (Photopsins are the photoreceptor proteins found in the cone cells of the retina that are the basis of color vision.) Those who see the dress color as white-gold have fewer blue color-sensitive cone cells and/or lesser amount of the specific photopsin. The similar effect can be demonstrated by a prolonged exposure of eyes to blue color which temporarily deplete the specific photopsin.


 

 

The sneaker debate: What color is this sneaker??

Internet erupts in debate over the color of these sneakers.

Question: Are they pink and white, or are they gray and teal?

What color is this sneaker?

the shoe thing @TFILDOLANS
What colour is this
10:54 AM - Oct 11, 2017

the shoe thing @TFILDOLANS, the Dutch Twitter user, who posted them indicated that they are not her shoes, but weighed in on the side of gray and teal.
the shoe thing @TFILDOLANS
ITS TEAL AND GREY
10:57 AM - Oct 11, 2017

She has several others taking her side.
But there is also a faction arguing hard for pink and white.

One user argues that the shoe is pink and just looks gray because of bad lighting and a low-quality camera.
@staruins (2:14 PM - Oct 11, 2017)
it’s originally pink & white, the flash & bad quality camera is what makes appear teal & grey or pink & white. here’s the original:

alisha @dolansmalik
THE REAL SHOE IS PINK & WHITE OKAY!
The second pic was with flash & darkened, so it looks teal & gray. (depends on what lighting ur in)

Keira Towle‏ @keirageorgi16
when i’m in my room it’s grey and downstairs it’s pink it’s making me go crazy.

alisha @dolansmalik
depends on the environment ur in. Natural light vs artificial light can have an effect.

d s y l m @swxxtalren
its still teal and grey in the first pic....

sam @samnichxls
the first pic still looks teal and grey.

Mia Bates @Mia_batesxo
It’s literally grey anywhere i look at it.
Hannah 🦄‏ @hannaheadyx
Are u blind !!! It’s clearly pink and white.

Darkboi‏ @Darkboi
The explanation makes every sense in the world but I’m blind as shit cause I still can’t see no pink lol

spooky sara @fool4dolans
BUT IF IT DEPENDS ON THE LIGHTING THAN WHY DO MY FRIENDS SEE IT DIFFERENTLY THAN ME?!

Why do two persons see it differently ?

There are three types of cone cells in the retina and each contains photopsin specifically for red, green or blue color. (Photopsins are the photoreceptor proteins found in the cone cells of the retina that are the basis of color vision.) Those who see the sneaker color as gray and teal have fewer red color-sensitive cone cells and/or lesser amount of the specific photopsin. The similar effect can be demonstrated by a prolonged exposure of eyes to red color which temporarily deplete the specific photopsin. This is called Color afterimage. (Reference: mesosyn.com After-image illusion)

Color afterimage
An interesting effect occurs when staring at a particular color for too long. Such action leads to an exhaustion of the cone cells that respond to that color - resulting in the afterimage. This vivid color aftereffect can last for a minute or more. For those who see the sneaker as pink, if your eyes have exposed to red color for more than a minute, the sneaker color may turn into grey-teal with light bluish-green shoe-lace/stripes.


Keep your face close to the right side of the monitor and stare at the small circle inside the red patch for 60 seconds, and afterward switch your view to the sneaker. The sneaker color may change from pink with whitish shoe-lace/stripes to grey-teal with light bluish-green shoe-lace/stripes.
You can darken the image to enhance the effect by tilting the monitor backward.
(Note: While staring at the small circle inside the red patch, you may also notice the decrease of intensity of redness. This is a sign of temporary depletion of red-specific photopsin.)

The hair debate: What color is her hair??

Question: Is the color of her hair pink, purple, violet, or blue?

Sabrina Abu-Obeid is a 24-year-old musician living in Florida. When she recently dyed her hair violet, her boyfriend noticed that her hair changed color under different lighting. He then had her walk from the kitchen to the bathroom to get the change on video as shown below:
The hair color change video
Click here to see the video on Youtube.


purple and violet
The hair color: pink, purple, violet, and blue

Answer and Explanation.

hair-color is violet under white light.
Yes, she did dye her hair violet. Therefore her hair will appear violet under the sunlight or bright white light in the kitchen. When she is out of the kitchen under dim white light, the color of her hair gets darker and turns blue. In other words, violet + black = blue. The dimmer the light, the bluish the hair color will be.




hair-color is violet under white light.
It appears that the light in the bathroom is a type of low pressure sodium vapor lamp which typically gives a distinctive yellow orange color as indicated here by the arrows. It is one of the most common lamps used in outdoor but can also be installed indoor. Her hair is pink-purple under brighter bathroom light and turns dark purple when she is out of the bathroom and is under dimmer light. In other words, violet + yellow-orange = purple.


 

 

Color-Changing Cake

Color-Changing Cake by CharlotteSometimes

Color-Changing Cake
Click here to see the video on Youtube.


Color-Changing Cake

Originally, the cake appears yellow, orange, and red. But spin the cake and suddenly those colors become purple, blue, and green.


CharlotteSometimes uploaded this YouTube video of a color-changing cake in November 2015. The video shows a cake with yellow, orange and red colors. However, when she spins the cake stand, the cake appears to change color like a chameleon and now have purple, blue and green colors.

The color-changing cake differs from the above dress and hair videos, which seemingly change colors in different lighting. In this case, the key is by airbrushing ridges of the cake frosting from one angle and then applying other colors at the ridges on the opposite side.

This isn’t video trickery, This is a real cake that really does change colors when you look at it from different angles. According to CharlotteSometimes the cake is 100% edible, it's just food coloring.



Other explanations.

www.reddit.com
Mellor88: "It's basically the same principle as "moving-image" toys.
The surface is like a zig-zag. All sides facing left are coloured with the first set of colours, and all side facing right coloured the opposite. The colour so see depends on where you stand."

Another reddit memeb explained."Use an airbrush and spray it from different sides with the different colors so that each color is only in one side of the ridges,"

Do the dark blue rows appear to slant? Surprise! They are completely straight and in parallel rows. The rows appear to skew due to the contrasts and variants in light and color as well as the varying angles of the diamond targets at the intersections. Blurring the image dissipates the illusion by dissolving the contrasts and angles.

These animated sculptures are freakishly hypnotizing

Some mathematicians will tell you that patterns exist all around us.
For John Edmark, an art lecturer at Stanford, patterns found in nature are the inspiration behind the mesmerizing sculptures called Blooms.
Each sculpture is 3D-printed and mimics patterns found in pinecones and sunflowers. They appear to come to life when rotated and filmed with a very slow shutter speed.

Blooms: Hypnotizing 3D Printed Sculptures Come Alive Under Strobe Lights

Hypnotizing effects of these trippy 3D-printed sculpture animations by artist John Edmark.
Drawing from spiral patterns and numerical sequences often found in natural objects like pine cones, cacti, sunflowers and seashells, the objects seem to shift and change before your eyes when spun under a strobe light.
Watching the videos of the sculptures in motion, it’s hard to believe these aren’t digital animations.

Can you spot what is wrong with this image?
At first glance, the photo appears to show three ladies having a sit down during a sunny walk.
But on close inspection, it becomes apparent that something is very wrong with the picture.
The odd photograph was shared on image sharing site Imgur and has left people scratching their heads in confusion.
On closer inspection of the picture, there three woman appear to be hovering in mid air - the seat on the bench is nowhere to be seen.

Five men sitting on a bench illusion

This is how!
At first glance, it looks like these guys are hanging out on a bench in this sitting optical illusion. However, upon closer inspection, you can clearly see that there actually is no bench, and they aren’t sitting on anything at all. Instead, they’re leaning their backs against the wall with their knees bent in a sitting position. The way that most of them are leaning forward, much like many people do when sitting, makes this illusion even more difficult to figure out. It also doesn’t help that the bottom of the brick wall they’re leaning against looks a little like a bench from far away. (www.moillusions.com)

Woman’s designer bag, is it white or blue?

White designer bag   Blue designer bag

Is it white or blue? A woman’s designer bag has sparked fierce debate online in Oct 2016.

Left image: White designer bag
Taylor Corso, from Mississippi, US, uploaded a snap of her new Kate Spade tote to Twitter along with the caption: “Everyone say hello to my new baby.”
Social media users rushed to compliment her “nice white purse” to which Taylor replied, “It’s blue”.
Her seemingly innocent comment sent the internet into meltdown.
“Oh come on, please. It is clearly white,” wrote one baffled contributor, while another added: “It is white to me, sorry to ruin the fun.”
How are people seeing blue?” questioned one confused guy.
“I feel like I’ve lost all sense of what colour means now,” pondered one puzzled commenter.

Right image: Blue designer bag
Taylor responded to the hundreds of comments by posting a second photograph of the bag taken in a different light.
This snap showed that it is clearly light blue.
The official colour of the pouch, which features two short handles, gold hardware and a long strap, is Mystic Blue.

These Two Images Are Actually Exactly The Same

These Two Images Are Actually Exactly The Same

These Two Images Are Actually Exactly The Same


The images you see before you are clearly different, one has dark red lips and the other, bright. Yet these images are, to all extents and purposes, completely the same.
How? Photoshop is the answer. The images are the same, it’s the backgrounds that are different. The lips and nails are filled with translucent red pixels.
When the image is placed on top of a dark background, the pixels are pronounced, showing the nails and lips to be a deep dark red. Place the same image on a white background and sure enough, the nails and lips are unrecognisably different.
