About this color
Rust sits at 15° on the color wheel with 74% saturation and 40% lightness, placing it in the red segment of the spectrum. At 74% saturation, the hue is fully legible and confident — richly chromatic without tipping into high-contrast territory. Its mid-range lightness positions it as a mid-tone: neither a background color nor a deep accent, but something in between.
In digital environments, Rust is rendered as rgb(177, 64, 27), where the red channel dominates at 177, creating a strongly red-skewed appearance. The mid-range lightness and strong saturation make this versatile for both foreground and background roles, depending on what it is paired against.
For print, Rust translates to a CMYK breakdown of 0C 64M 85Y 31K. With a moderate key (31%), this color uses black to deepen the chromatic channels rather than replace them, a profile that typically holds up well in both offset and digital print.
