RAL 100 20 10
Deep Spruce
RAL 100 20 10 Deep Spruce sits at hue 100, lightness 20, and chroma 10 in the RAL Design system, producing a very dark muted blue-green with the depth of old spruce bark and deep tidal pools. This restrained tone is favoured for heritage park gate finishes, coastal shelter exterior trim, and conservation area fencing details. Its low lightness and minimal chroma create a colour that reads nearly black in shadow yet reveals a cool blue-green undertone under direct light.
Color Reference
The RAL Design system uses Hue-Lightness-Chroma (HLC) notation. Hue describes the color family (0-360°), Lightness describes brightness (0-100), and Chroma describes saturation intensity (0-100+).
