RAL 350 25 20
Dark Terracotta Earth
RAL 350 25 20 Dark Terracotta Earth occupies hue 350, lightness 25, and chroma 20, a deep saturated warm amber that recalls the concentrated warmth of fired terracotta and the rich interior of old Tuscan wine cellars. It is ideal for heritage library interior finishes, artisan pottery studio coordination, and traditional joinery details. The strong chroma at this dark level gives it a clay-fired intensity that feels rooted in centuries of Mediterranean ceramic craft.
