About this color

Green Kelp sits at 92° on the color wheel with 23% saturation and 16% lightness, placing it in the green segment of the spectrum. Its restrained 23% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors. The lower lightness gives it weight and depth, lending gravity to any palette it enters.

In digital environments, Green Kelp is rendered as rgb(40, 50, 31), where the green channel leads at 50, 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, Green Kelp translates to a CMYK breakdown of 20C 0M 38Y 80K. A substantial black component (80%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks.
