About this color

Bitter sits at 72° on the color wheel with 10% saturation and 50% lightness, placing it in the yellow segment of the spectrum. Its restrained 10% 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, Bitter is rendered as rgb(135, 140, 115), where the green channel leads at 140, with red and blue channels close behind. This muted, medium-toned character adapts well to supporting roles: borders, disabled states, secondary text, and structural UI elements.

For print, Bitter translates to a CMYK breakdown of 4C 0M 18Y 45K. With a moderate key (45%), 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.
