RAL 100 25 35
Rich Viridian
RAL 100 25 35 Rich Viridian is positioned at hue 100, lightness 25, and chroma 35, a deep saturated blue-green that evokes the concentrated pigment of viridian and deep ocean kelp forests. It is specified for botanical garden structural elements, nature reserve signage, and luxury garden furniture finishes. The strong chroma at very low lightness produces a colour of concentrated mineral energy and oceanic depth.
