About this color
Black Rock sits at 257° on the color wheel with 88% saturation and 10% lightness, placing it in the blue-violet segment of the spectrum. With saturation at 88%, this is a high-chroma color: the kind that anchors palettes and demands considered placement. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.
In digital environments, Black Rock is rendered as rgb(16, 3, 48), where the blue channel is highest at 48, anchoring the color in the cool register. High saturation combined with low lightness creates deep, jewel-toned results — useful for premium UI elements, hover states, and focused interaction areas.
For print, Black Rock translates to a CMYK breakdown of 67C 94M 0Y 81K. The dominant black channel (81%) 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.
