About this color
Outer Space sits at 189° on the color wheel with 25% saturation and 20% lightness, placing it in the cyan segment of the spectrum. Its restrained 25% 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, Outer Space is rendered as rgb(38, 60, 64), where the blue channel is highest at 64, though it sits close to the other channels. 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, Outer Space translates to a CMYK breakdown of 41C 6M 0Y 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.
