About this color
Swamp sits at 199° on the color wheel with 37% saturation and 10% lightness, placing it in the blue segment of the spectrum. The moderate 37% 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, Swamp is rendered as rgb(16, 29, 35), where the blue channel is highest at 35, 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, Swamp translates to a CMYK breakdown of 54C 17M 0Y 86K. The dominant black channel (86%) 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.
