About this color

Heavy Metal sits at 70° on the color wheel with 12% saturation and 20% lightness, placing it in the yellow 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. The lower lightness gives it weight and depth, lending gravity to any palette it enters.

In digital environments, Heavy Metal is rendered as rgb(55, 57, 45), where the green channel leads at 57, with red and blue channels close behind. Low saturation at this depth produces the kind of sophisticated, near-neutral dark that works for application shells, sidebars, and dark-mode base layers.

For print, Heavy Metal translates to a CMYK breakdown of 4C 0M 21Y 78K. A substantial black component (78%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks. No brands in the brandkit.pro library currently specify this exact hex as a named brand color.
