Color Psychology

Medium gray represents balance, neutrality, and diplomatic composure. It is the color of concrete, steel, and overcast skies, suggesting urban modernity and industrial strength. Gray communicates professionalism and impartiality in equal measure.

Medium gray is essential for body text, icons, and secondary labels in user interfaces. It provides the typographic backbone of design systems, separating primary from secondary information.
