RAL 280 20 10
Deep Olive Dusk
RAL 280 20 10 Deep Olive Dusk sits at hue 280, lightness 20, and chroma 10 in the RAL Design system, producing a very dark muted yellow that evokes the concentrated depth of aged olive oil and the shadowed interior of medieval granaries. This intense tone is favoured for heritage museum display cases, luxury cigar lounge interior finishes, and antique frame restoration details. Its low lightness and restrained chroma create a colour that reads nearly black yet reveals a warm olive-yellow heart under direct illumination.
