RAL 030 40 25

Warm Umber

RAL 030 40 25 Warm Umber sits at hue 030, lightness 40, and chroma 25, a warm earthy mid-dark orange reminiscent of raw umber pigment and sun-dried clay. It is specified for safari lodge interior schemes, natural stone colour coordination, and artisan workshop fittings. The moderate chroma and darkness produce a colour that feels organic, grounded, and connected to natural landscapes.
