About this color

Bunker sits at 240° on the color wheel with 6% saturation and 10% lightness, placing it in the blue segment of the spectrum. At near-zero saturation, it reads as a pure near-black neutral, with hue playing almost no role in its character. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.

In digital environments, Bunker is rendered as rgb(24, 24, 27), where the blue channel is highest at 27, though it sits close to the other channels. 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, Bunker translates to a CMYK breakdown of 11C 11M 0Y 89K. The dominant black channel (89%) does most of the tonal work here — cyan, magenta, and yellow contribute minimally, so the printed result will be a deep, near-neutral tone that reads differently from its screen equivalent. No brands in the brandkit.pro library currently specify this exact hex as a named brand color.
