Black and White has been popular colors in Executive work place dressing for many years. You may call this style a Uniform. For a job interview you cannot go wrong with a black suit and a white shirt. So, Are black and white colors? Ask a scientist and you'll get a reply based on physics: “Black is not a color, white is a color.” Ask an artist or a child with crayons and you'll get another: “Black is a color, white is not a color.” Or is it?  According to Encyclopedia Britannica . . "Color, in terms of pigment, is every shade and hue found in a brand new box of crayons (and any combination you could make from them). To put it in scientific terms, however, color is simply the range of visible light that humans can see".   I love a good fitting pair of black pants and they go with every color in my crayon box. Both the pants & top in this look have been sitting in my closet waiting to be worn.
