Recently, a new optical illusion internet sent to a ticzzy. In this, a group of elephants was arranged in a circle. When they were on the first look, they all looked to be blue-purple in color (or rather violet), some of them as they looked more purple, seemed more purple than the other. Let’s find out more …The illusion of being more purpleThe picture was shared on IG by the Sciencemagician, who wrote: “Which elephant do you perceive as the most purple in color?For best results, turn your screen brightness up. Works best on newer OLED screens. Unfortunately will not work on pressure. This illusion is based on a new scientific paper that I read by Hinnerck Schultz-Hildebrant. It is a fascinating combination of mechanisms in our vision system and color theory. Search for “when purple is only perceived when fixing: a fixation and distance -dependent color illusion” to read the paper as an oppression. “Let’s find out more …More about the illusionHinnerck Schultz-Hildebrant discovered the new optical illusion “when purple was perceived only during fixation” which shows purple areas shows its real purple color, when they are directly observed but turns blue when seen from the side. The color appearance of purple structures depends on both display distance and fixation point position, as longer distances can restore purple visibility in some cases. The brain constructs color perception through this illusion that shows how purple perception works differently than other colors because Fovea lacks direct conflict for purple.How it worksThe human eye uses Fovea central vision to process color information that creates this illusion.S-Cone Absce: Fovea contains minimal S-cones that work to detect blue light. The brain must create purple perception through signal reconstruction, when we focus on a point because Fovea lacks sufficient detection of blue light.The brain uses peripheral cone signals along with contextual information to interpret purple as blue as the eyes move away from the central viewing point.The distance between the viewer and the subject determines which purple elements will be shown purple again, as fixation distance affects the visual perception.Why it’s so interestingThe brain’s adaptation process to stimulation becomes visible through this illusion, as it shows how color perception transforms based on time and environmental conditions.The illusion shows advanced knowledge about color theory and visual system operation, as it shows how the brain builds color beliefs from eye signals.The brain generates misleading perceptions through this contemporary optical illusion, which shows its ability to create misleading perceptions from received information.Types of optical illusionsThere are three main types of optical illusions:Literal illusions: These occur when the brain combines elements in an image to create something that does not exist. For example, an image may look like two faces or a vase depending on how you interpret it.Physiological illusions: These are caused by overstimulation of the visual system, such as excessive exposure to light, movement or color. They can create effects such as imitated or motion -millionaire.Cognitive Illusions: These rely on how the brain consciously interprets information. Examples include illusions such as the Müller-Lyer illusion, where lines appear longer or shorter due to surrounding forms.
