RAL 010 40 20
Muted Brick
RAL 010 40 20 Muted Brick sits at hue 010, lightness 40, and chroma 20, a warm earthy red reminiscent of aged brickwork and natural clay. Architects use it for terracotta-inspired facade panels, artisan workshop fittings, and rustic interior accent elements. Its low saturation and moderate darkness give it an organic, grounded character that connects built environments to natural materials.
