RAL 140 20 15
Deep Navy
RAL 140 20 15 Deep Navy sits at hue 140, lightness 20, and chroma 15 in the RAL Design system, producing a very dark muted blue that evokes the solemn depth of naval dress uniforms and midnight Atlantic waters. This restrained tone is favoured for naval heritage structural finishes, formal interior panelling, and ceremonial signage details. Its low lightness and moderate chroma create a colour that reads nearly black in shadow yet reveals a true blue undertone under direct light.
Color Reference
