About this color
Neptune sits at 184° on the color wheel with 27% saturation and 60% lightness, placing it in the cyan segment of the spectrum. Its restrained 27% saturation keeps the hue subtle — present but not assertive, making it easy to layer over or under more expressive colors.

In digital environments, Neptune is rendered as rgb(125, 177, 181), where the blue channel is highest at 181, though it sits close to the other channels. Muted saturation at high lightness is a classic formula for soft background fills, placeholder states, and secondary surface colors in light-mode interfaces.
For print, Neptune translates to a CMYK breakdown of 31C 2M 0Y 29K. With a moderate key (29%), 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.
