About this color

Aluminium sits at 215° on the color wheel with 12% saturation and 70% lightness, placing it in the blue segment of the spectrum. Its restrained 12% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors.

In digital environments, Aluminium is rendered as rgb(169, 177, 188), where the blue channel is highest at 188, though it sits close to the other channels. Muted saturation at high lightness is a classic formula for soft background fills, placeholder states, and secondary surface colors in light-mode interfaces.

For print, Aluminium translates to a CMYK breakdown of 10C 6M 0Y 26K. With a moderate key (26%), this color uses black to deepen the chromatic channels rather than replace them, a profile that typically holds up well in both offset and digital print.
