About this color

Biscay sits at 240° 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, Biscay is rendered as rgb(54, 54, 99), where the blue channel is highest at 99, anchoring the color in the cool register. 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, Biscay translates to a CMYK breakdown of 45C 45M 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.
