About this color

Oil sits at 19° on the color wheel with 29% saturation and 15% lightness, placing it in the red segment of the spectrum. Its restrained 29% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors. Near-black lightness makes it read as a deep, absorptive tone — color is implied more than seen.

In digital environments, Oil is rendered as rgb(49, 34, 27), where the red channel dominates at 49, 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, Oil translates to a CMYK breakdown of 0C 31M 45Y 81K. The dominant black channel (81%) does most of the tonal work here — cyan, magenta, and yellow contribute minimally, so the printed result will be a deep, near-neutral tone that reads differently from its screen equivalent. No brands in the brandkit.pro library currently specify this exact hex as a named brand color.
