About this color
Mineral Green sits at 158° on the color wheel with 18% saturation and 30% lightness, placing it in the cyan segment of the spectrum. Its restrained 18% 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, Mineral Green is rendered as rgb(63, 90, 80), where the green channel leads at 90, 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, Mineral Green translates to a CMYK breakdown of 30C 0M 11Y 65K. A substantial black component (65%) 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.
