These Strawberries Are Not Red | WIRED
What is color constancy and how does it trick our brain into seeing colors that aren’t really there? WIRED’s Robbie Gonzalez and neuroscientist David Eagleman use ambiguous photographs and giant props to explain light, color and the science of illusions.

@Lung Boy It is edited, lol; the whole thing is tinted light blue. The original image (which isn’t shown in this video) has actually red strawberries.

@SirYodaJedi I still don’t think that’s true but either way, the illusion/phenomenon taking place is real and the guy in the original comment is making it sound like it’s not

The physical color gray requires red. 120,120,120 is still 120 red. If it is 180,178,178 that is still a gray that is more red.

Generally speaking all fruit you buy in almost all stores start as unripe – they start with unripe (such as green apples) then use rapid ripening processes such as radiation to fast ripen the fruit (and vegetables), it would generally be impossible to get the massive amount of fruits and vegetables t o market in the ripe status.
This may vary a bit if for example a farmer picks them and sells them. But yes the photo is an illusion that tricks the eye
I'm right you're wrong
October 17, 2021 at 5:52 pm
nope, not at all.
Dave Alexander
October 17, 2021 at 5:30 pm
Wrong. The CMYK color value for gray is 0% Cyan, 0% Magenta, 0% Yellow, 50% Black.
If that image has ANY Cyan, Magenta or Yellow in it, it is NOT gray.
Use a spectrophotometer, measure it and tell us what the values are.
Guaranteed they are not 0,0,0,50 or that picture would look, um … GRAY.
Dave Alexander
October 17, 2021 at 6:13 pm
@Joshua Kallenberg Nope. Not buying it. Need the exact CMYK to say what color it is. However, being someone who works with Photoshop and color palletes every day all day, I sampled the video (which is not 100% accurate given the limitations of RGB phosphors, but is close) and that color at the tip of the strawberry is Cyan 58%, Magenta 31%, Yellow 32% and Black 1%, which makes that color Reddish Gray. Which is exactly what he was saying that color ISN’T.

@Dave Alexander what’s odd is the fact that before 24 seconds the picture looks like it has much more of a blueish hue, but after 24 seconds the strawberries appear much more red.
Dusty B
October 17, 2021 at 7:27 pm
@Carlos Right? I was like “kinda blueish gray I guess?”, and at the end when they cut back to the picture close up it looks red.

October 17, 2021 at 7:31 pm
cool, have you personally checked if that tile isnt 0,0,0,50? if not then how can you say for sure its not grey and taht he is wrong?
Dave Alexander
October 17, 2021 at 7:44 pm
@Carlos I just sampled two areas pre- and post-24 seconds.
Pre-24 Red Part of a Strawberry is 57,32,31,1
Post-24 Red Part of a Strawberry is 51,36,38,2
Pre-24 deepest shadow in image is 82,28,41,3
Post-24 deepest shadon in image is 84,25,45,3
That means in the two images, the delta for the berry is -6C, +4M, +7Y, +1K – a lot less Cyan and a lot more Magenta and Yellow
the delta for the shadow is +2C, -3M, +4Y, 0K – more Yellow but pretty close otherwise
These fall into the parameters of JNDs (Just Noticable Differences, it’s an actual color science term you can look up), which each human distinguishes differently. That means you can see that the berries are noticebly redder after 24 seconds and many people cannot.

All these people saying its not grey unless it has a certain value but never actually show proof of them selves checking the tile physically or digitally. Like what is the point of your comment, its irrelevant unless you actually make a statement about the video with it.

Keeping in mind colour constancy as an artist is very important, otherwise you’d never be able to get good colours and lighting. All perceived colours are relative to other colours.
Andrew Griggs
October 17, 2021 at 10:18 pm
Hold on, they have to be red. Elsewise how do you get the image? Typically can’t shoot a grey image onto a grey screen and see it. The color of the strawberries has to be there.

The strawberries are red, this picture of those red strawberries is just somewhat desaturated. Anyone not color-blind can see that, you’re using the language wrong here.
Catherine W.
October 18, 2021 at 1:16 am
No really there is no red in the image. You can take a simple screenshot of the image and put it into any art software, no red to be found, the shades of gray are actually more blue or green leaning. Even if you apply a filter to remove all the red in the image nothing changes.

That is because they are (more like turquiose, but close to blue), Photoshop color picker showed a color 84a3ab for example. These strawberries are not gray by any means. I see them reddish though.

Even when you took out the little piece I still see it as a green grey red mixture it’s not a bright red it’s not a regular gray and it’s not a vibrant blue and there’s also a very odd tint of green
Sapphire
October 21, 2021 at 9:31 pm
What color are the strawberries? Red. The actual strawberries are red. You wanna talk about what color they APPEAR in that image? Okay fine. But the fruits themselves were red. Unless the artist grew gray strawberries, which I doubt very much. Applying a color filter over the photograph doesn’t change the original color of the fruit. 😛

October 30, 2021 at 7:44 pm
That’s because your brain subconsciously think that strawberries are red, because grey contains more red in the RGB scale than blue. It is a very common way to make something look red without making it actually red in art.
