RAL 150 45 15

Warm Admiral

RAL 150 45 15 Warm Admiral sits at hue 150, lightness 45, and chroma 15, a muted earthy mid-dark blue reminiscent of admiral's dress coats and overcast North Atlantic waters. It is specified for naval interior elements, heritage millwork finishes, and natural material colour coordination. The moderate chroma and darkness produce a colour that feels mineral, grounded, and connected to maritime traditions.
