RAL 310 45 15
Warm Willow Bark
RAL 310 45 15 Warm Willow Bark sits at hue 310, lightness 45, and chroma 15, a mid-dark green-yellow with earthy warmth reminiscent of willow bark and the shadowed interior of old garden pavilions. It is specified for garden centre interior elements, heritage millwork finishes, and café dining room surfaces. The balanced chroma and moderate darkness produce a colour that feels organic, grounded, and connected to the warmth of English garden traditions.
