About this color
River Bed sits at 206° on the color wheel with 23% saturation and 30% lightness, placing it in the blue 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, River Bed is rendered as rgb(59, 79, 94), where the blue channel is highest at 94, 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, River Bed translates to a CMYK breakdown of 37C 16M 0Y 63K. A substantial black component (63%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks.
