About this color
Celtic sits at 133° on the color wheel with 24% saturation and 15% lightness, placing it in the green 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, Celtic is rendered as rgb(29, 47, 33), where the green channel leads at 47, with red and blue channels close behind. 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, Celtic translates to a CMYK breakdown of 38C 0M 30Y 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.
