About this color

Chartreuse sits at 90° on the color wheel with 100% saturation and 50% lightness, placing it in the green segment of the spectrum. With saturation at 100%, this is a high-chroma color: the kind that anchors palettes and demands considered placement. 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, Chartreuse is rendered as rgb(128, 255, 0), where the green channel leads at 255, producing a distinctly green-dominant tone. The mid-range lightness and strong saturation make this versatile for both foreground and background roles, depending on what it is paired against.

For print, Chartreuse translates to a CMYK breakdown of 50C 0M 100Y 0K. With almost no black ink (0%), this color is built almost entirely from process inks: 50% cyan, 100% yellow. This profile tends toward vibrancy in print, though ink density limits on press may affect saturation on coated versus uncoated stock.
