About this color

Black sits at 240° on the color wheel with 11% saturation and 2% lightness, placing it in the blue segment of the spectrum. Its restrained 11% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.

In digital environments, Black is rendered as rgb(4, 4, 5), where the blue channel is highest at 5, 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, Black translates to a CMYK breakdown of 20C 20M 0Y 98K. The dominant black channel (98%) 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 Hulu Dark.
