There are many different ways of looking at things. That is a fact. Some see black, others see the white in the picture, others with an eye for detail can see where the black ends – clearly. How I wish I were one of those with an eye for detail!
Those that see black and white probably have life easiest, if you can differentiate the black from the white it makes it easier to pick out either color, so everything can be arranged, categorized, sorted and you only have to decide between two very distinctly different colors.
