About this color

Comet sits at 237° on the color wheel with 11% saturation and 40% lightness, placing it in the blue segment of the spectrum. Its restrained 11% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors. 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, Comet is rendered as rgb(91, 92, 113), where the blue channel is highest at 113, though it sits close to the other channels. This muted, medium-toned character adapts well to supporting roles: borders, disabled states, secondary text, and structural UI elements.

For print, Comet translates to a CMYK breakdown of 19C 19M 0Y 56K. A substantial black component (56%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks.
