RAL 280 35 25
Dark Mustard
RAL 280 35 25 Dark Mustard is defined by hue 280, lightness 35, and chroma 25, a bold dark yellow that carries the pungent warmth of stone-ground mustard seed and the deep glow of aged turmeric root. It is a natural choice for gourmet food branding elements, heritage pub signage details, and artisan condiment packaging surfaces. The strong saturation at this dark level gives it a spicy, appetizing quality that commands attention in food-related and heritage design contexts.
