#8F8F8F
RAL color
Grey Aluminium (#8F8F8F) is a medium grey from the RAL Classic system, the darker counterpart to White Aluminium, used for architectural aluminium profiles and components requiring a more substantial, less reflective grey than the lighter variant. Applied to window frames, structural aluminium, and facade systems where a mid-tone grey is preferred over near-white, it provides a confident, contemporary appearance. 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.
