About this color
Vulcan sits at 210° on the color wheel with 35% saturation and 9% lightness, placing it in the blue segment of the spectrum. The moderate 35% saturation gives it enough color presence to register clearly without competing for dominance in a composition. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.
In digital environments, Vulcan is rendered as rgb(15, 23, 31), where the blue channel is highest at 31, though it sits close to the other channels. This cool mid-tone is a reliable choice for UI chrome, informational states, and contexts that call for a calm, readable presence.
For print, Vulcan translates to a CMYK breakdown of 52C 26M 0Y 88K. The dominant black channel (88%) 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.
