Black is the absence of light. Unlike white and other hues, pure black can exist in nature without any light.
Some consider white to be a color because white light comprises all hues on the visible light spectrum. ... But in a technical sense, black and white are not colors; they’re shades. Something is often presented in black and white to make a symbolic reference or inference to something that might only exist in the mind. The possibilities are endless as to what the original thoughts’ colors might be.
