About this color
Steel Gray sits at 253° on the color wheel with 24% saturation and 15% lightness, placing it in the blue segment of the spectrum. Its restrained 24% 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, Steel Gray is rendered as rgb(33, 29, 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, Steel Gray translates to a CMYK breakdown of 30C 38M 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. No brands in the brandkit.pro library currently specify this exact hex as a named brand color.
