The even neutrality ensures compatibility with a wide range of building material palettes.

色彩心理学

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.

Design Usage

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. Ensure proper contrast ratios since many popular mid-gray values fall below WCAG AA for text on white backgrounds.
