About this color

Kelp sits at 69° on the color wheel with 11% saturation and 23% lightness, placing it in the yellow segment of the spectrum. Its restrained 11% 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, Kelp is rendered as rgb(63, 65, 52), where the green channel leads at 65, 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, Kelp translates to a CMYK breakdown of 3C 0M 20Y 75K. A substantial black component (75%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks. No brands in the brandkit.pro library currently specify this exact hex as a named brand color.
