Background A mysterious sneaker that surfaced on the internet in recent times sparked a debate as to whether its actual color is green and grey or pink and white. It was hypothesized that left cerebral dominance was associated with perceiving the sneaker in green and grey color. However, there were no studies done to prove it and propose a scientific explanation for the phenomenon.

Objective

To study the role of cerebral dominance as a predictor of differential color perception, factors influencing it and hypothesize possible underlying mechanisms for the same

Design/Methods Random healthy people from the population above 16 years age, without any underlying ophthalmological disorder, other than refractive error were shown the sneaker picture to identify the colour. Handedness ascertained through handedness inventory was used as a surrogate for cerebral dominance. Age, sex, refractive error- type and severity, colour blindness if any, colour with and without glasses were analysed.

Results Of the 343 people studied in the ages 16-87 years, 51.02% (175/343) were females. 74.34% perceived the shoe colour as grey and green while 23.91% as pink and white.327 were right handed (95.34%),6 (1.75%) were left handed and rest ambidextrous.Myopia was the most common refractive error (88/343; 25.66%). Among the right handers, 77.33% (249/322) saw grey and green. Older age (p=0.01), right handedness (p=0.001) and hypermetropia (p=0.018) showed significant association with the perception of green and grey color. Higher percentage of myopics perceived pink and white (p=0.072).

Conclusions Genetic and age mediated differences in the lens shape, relative composition of cone types and threshold sensitivities to different colours, anatomical and physiological differences in colour processing areas between the right and left cerebral hemispheres are few plausible explanations. fMRI studies to explore the differences in the extent and activation of the involved networks further strengthen the concept of cerebral dominance in colour vision
