About this color

Birch sits at 40° on the color wheel with 24% saturation and 20% lightness, placing it in the orange-red segment of the spectrum. Its restrained 24% 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, Birch is rendered as rgb(63, 55, 39), where the red channel dominates at 63, though the other channels keep the hue balanced. 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, Birch translates to a CMYK breakdown of 0C 13M 38Y 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.
