RAL 170 30 30
Rich Byzantium
RAL 170 30 30 Rich Byzantium is positioned at hue 170, lightness 30, and chroma 30, a deep saturated violet that channels the opulence of Byzantine mosaics and the concentrated pigment of Tyrian purple. It is specified for luxury brand accent elements, gallery feature wall finishes, and premium automotive detail coatings. The strong chroma at low lightness produces a colour of regal intensity and historical resonance.
