About this color

Mercury sits at 192° on the color wheel with 10% saturation and 90% lightness, placing it in the cyan 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. The elevated lightness keeps it airy and open, well-suited to large surface areas without visual weight.

In digital environments, Mercury is rendered as rgb(227, 231, 232), where the blue channel is highest at 232, 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, Mercury translates to a CMYK breakdown of 2C 0M 0Y 9K. The low-to-moderate black value (9%) means the color's character in print comes primarily from its cyan ink content (2%), with black serving as a supporting shadow tone.
