About this color
Seaweed sits at 87° on the color wheel with 61% saturation and 10% lightness, placing it in the green segment of the spectrum. At 61% saturation, the hue is fully legible and confident — richly chromatic without tipping into high-contrast territory. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.
In digital environments, Seaweed is rendered as rgb(27, 41, 10), where the green channel leads at 41, with red and blue channels close behind. High saturation combined with low lightness creates deep, jewel-toned results — useful for premium UI elements, hover states, and focused interaction areas.
For print, Seaweed translates to a CMYK breakdown of 34C 0M 76Y 84K. The dominant black channel (84%) 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.
