Deep Amethyst

RAL 170 20 20 Deep Amethyst sits at hue 170, lightness 20, and chroma 20 in the RAL Design system, producing a very dark saturated violet that evokes the mineral depth of uncut amethyst crystals and the last light of a winter evening. This concentrated tone is favoured for theatre interior finishes, luxury packaging accents, and formal reception panelling. Its low lightness and moderate chroma create a colour that reads nearly black in shadow yet reveals a rich violet heart under direct illumination.
