RAL 000 30 00
Dark Slate
RAL 000 30 00 Dark Slate is positioned at lightness 30 on the grey axis, a very dark grey that approaches black while retaining enough lightness to show surface texture and form. It is a popular choice for roofing elements, security fencing, and premium appliance finishes where near-black drama is wanted without total light absorption. Paired with lighter greys from the same axis, it creates striking tonal compositions.
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+).
