RAL 350 30 25

Rich Sienna Clay

RAL 350 30 25 Rich Sienna Clay is positioned at hue 350, lightness 30, and chroma 25, a deep high-chroma warm amber that channels the concentrated fire of raw sienna pigment and the molten glow of kiln-fired earthenware. Designers specify it for luxury automotive accent coatings, gallery feature wall finishes, and premium brand identity elements. The strong chroma at low lightness produces a colour of earthy intensity and dramatic warmth, recalling the prized sienna pigments of Renaissance painters.
