The most famous example for perceiving colors differently is the blue-black or white-gold dress widely discussed in 2015. The brain of people who interpret ambient light as too blue compensates for it. It takes out blue color like a filter in your photo-shop software. Consequently, these people see the dress white and gold. On the contrary, when their brain feels that the ambient light is not blue enough, they perceive the dress as black and blue. Obviously, color perception varies among people, and color perception seems to be related to the DNA. However, when told the correct colors people can see it both ways. Note that this illusion exists also for other colors.
