407 Clay — The Earth-Tone Brown
So Fine! 407 Clay is the warm, slightly reddish medium brown of fired clay — a colour with both earthy grounding and warm red character. For Southwestern, heritage, and earth-tone quilts where brown should feel warm and earthy, Clay integrates naturally on the full range of warm brown-to-terracotta fabrics. It deepens the neutral run from 404 Mushroom, with 424 Chocolate and 426 Ginger extending the brown family into darker and spicier territory.
