Strawberries are not red in any way shape or form
If you are seeing red, your mind is playing tricks on you.
They are actually grey with a hint of green. Yes. Grey and green.
This isn’t one of those The Dress moments whereby the colour clearly changes from white and gold to red and black, it’s all grey and green.
The picture is an optical illusion.
It’s actually an example of colour constancy – whereby your brain is trying to rationalise the image.
One expert said that when you add a cyan tint to a black and white picture it shifts colours in the opposite direction.
If you look at the rectangles on the picture below you can see that they’re grey.
We used editing software to pick one of the most ‘red’ parts of the picture and this is what we found.
You can go one step further and do what this guy did in isolating a few colours.
Bevil Conway, a visual perception expert, explained that it’s all about light entering the eyes at different wavelengths.
He told Motherboard: ‘If you imagine walking around outside under a blue sky, that blueness is, in some sense, colour-contaminating everything you see.
‘If you take a red apple outside under a blue sky, there are more blue wavelengths entering your eye.
‘If you take the apple inside under a fluorescent or incandescent light without that same bias, the pigments in the apple are exactly the same but because the spectral content of the light source is different, the spectrum entering your eye that’s reflected off the object is different.’
Clear?
The original image was put online by Akiyoshi Kitaoka and this is what it looks like – not quite as ‘red’, but still… it’s a pretty awesome demonstration of colour constancy.
