About this color
Blue Dianne sits at 199° on the color wheel with 29% saturation and 30% lightness, placing it in the blue 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. The lower lightness gives it weight and depth, lending gravity to any palette it enters.
In digital environments, Blue Dianne is rendered as rgb(54, 85, 99), where the blue channel is highest at 99, 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, Blue Dianne translates to a CMYK breakdown of 45C 14M 0Y 61K. A substantial black component (61%) anchors this color in print. The remaining ink channels supplement rather than drive the hue, which keeps the result stable across different paper stocks.
