It ’s name the McCollough impression — named after psychologist Celeste McCollough Howard — and one of the earlieststudiesof this phenomenon dates back to 1975 . research worker separated 16 people into five mathematical group and showed them two different stripy patterns featuring the colors red and light-green .
After looking at each image for about three minutes , the test subjects then stared at disastrous and white striped grids . That ’s when the force started to put in , and participants reported seeing a pinkish hue in the black and white range of a function . One test group reported that the effect stay on in full strength after five days , while the other four mathematical group said they still palpate a weakened form of the effects three months later .
An earlier study from 1969 witness that only the color green and red produced this effect . There ’s no consensus on what make it , but some scientists conceive it ’s related to neurons in the ocular cerebral mantle , according toIFL Science . Others have suggested that the psyche endeavor to “ color - right ” what you ’re seeing , while a third possibility posits that the effect is a symptom of withdrawal triggered by the absence seizure of color .
To get your imagination back to normal more quickly , it ’s recommended that you stare at the two images of the red and unripened lines , except with the image turned 90 degrees counter - clockwise .
