About this color

Reef sits at 101° on the color wheel with 100% saturation and 80% 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.

In digital environments, Reef is rendered as rgb(185, 255, 153), where the green channel leads at 255, producing a distinctly green-dominant tone. High saturation at this lightness produces strong contrast against white — effective for CTAs, badges, and elements that need to stop the eye.

This profile tends toward vibrancy in print, though ink density limits on press may affect saturation on coated versus uncoated stock.
