Color's way of flexing that it never needed color to begin with.

means Using only one color (or shades of black, white, and gray) rather than a full palette.

from From Greek monos ('single') plus chroma ('color'), the same chroma that gives us 'chromatic' and 'chromosome' (literally 'colored body,' for how the structures took up lab dyes). The word entered English in the 1800s to describe art and later photography done in a single hue — black-and-white film being the most famous case of a medium wearing its monochrome on purpose.
