About this color

Shark sits at 213° on the color wheel with 13% saturation and 16% lightness, placing it in the blue segment of the spectrum. Its restrained 13% 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, Shark is rendered as rgb(36, 41, 47), where the blue channel is highest at 47, 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, Shark translates to a CMYK breakdown of 23C 13M 0Y 82K. The dominant black channel (82%) 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. In brand applications, this exact value is specified as GitHub Dark.
