Sabrina Abu-Obeid is a 24-year-old vlogger and musician living in Florida. When she recently dyed her hair violet her boyfriend, DJ Monopoli, noticed that the violet color appeared pink, purple or blue under different lighting. He then had her walk through various rooms to get the change on camera — just in case he was going insane.
As you can see from the video, Monopoli's general take on the illusion is "Whoaaaaa."
