"If there's one thing the internet loves, it's a good optical illusion. The most recent brain-boggling viral hit is this deceptively simple purple elephant illusion that appears to transform right before our eyes, despite no video trickery involved. From the cognitive to the physiological, optical illusions come in all forms, constantly proving that we can't always believe our eyes. Even when the science behind the visual trick is revealed, optical illusions still manage to perplex and amaze all corners of the internet."
"Shared by Science Magician, Matt Pritchard, this optical illusion consists of a circle of vivid purple elephants in a circle. The aim is to find which one is the brightest, but the more you search, the less clear it becomes, as each appears more vibrant than the last. "This illusion is based on a new science paper I read by Hinnerck Schultz-Hildebrant. It's a fascinating combination of mechanisms in our vision system and colour theory," Matt explains on Instagram."
A viral purple-elephant optical illusion shows a ring of vivid purple elephants and challenges viewers to identify the brightest. Viewers repeatedly fail to settle on a single brightest elephant because neighboring elements appear to vary in apparent brightness. The percept arises from a combination of visual-system mechanisms and colour theory linked to a recent scientific paper by Hinnerck Schultz-Hildebrant. The effect intensifies on brighter displays, particularly OLED screens. The illusion exemplifies how cognitive and physiological processes in vision can produce convincing but misleading perceptions of colour and luminance.
