În cadrul videoclipului, în timp ce psihologul mută un pătrat de-a lungul foii de hărtie, iar acesta îşi schimbă culoarea. Conform Mail Online unele persoane ce au vizionat imaginile au afirmat că videovlipul a fost trucat.
Însă toate pătratele au aceaşi culoare. Există o explicaţie foarte simplă pentru modul în care acestea par că îşi schimbă culoarea. Efectul este rezultatul percepţiei luminii sau a faptului că ochiul uman percepe culorile diferit în funcţie de obiectele din fundal sau din prim-plan. Dacă există un fundal luminos obiectul din prim-plan va părea mai întunecat. Alţi factori precum cantitatea de lumină reflectată de către o suprafaţă, sau orientarea suprafeţei pot produce efecte similare.
În 2014, un profesor din cadrul Universităţii din Washington prezenta fenomenul. „Percepţia reflexiei suprafeţei reprezintă o problemă computaţională semnificativă pentru sistemul vizual,” au declarat Maria Pereverzeva şi Scott O. Murray, autorii studiului. Kitaoka a replicat acelaşi efect în alte videoclipuri similare.
