Act as a professional logo designer with 10+ years of experience in crafting organic, artisanal brand identities. Design a minimalist yet expressive logo for a handmade pottery studio called [STUDIO_NAME], specializing in [CERAMIC_STYLE, e.g., rustic stoneware or delicate porcelain]. The logo should evoke [KEY_THEME, e.g., earthy warmth, modern elegance] through subtle textures, fluid lines, and a muted color palette. Incorporate abstract pottery silhouettes or tool motifs (like a stylized wheel or kiln) while maintaining scalability for stamps, packaging, and digital use. Avoid clichés like obvious pot shapes—focus on craftsmanship symbolism. Deliver 3 refined black-and-white concepts first, then develop the chosen one with 2 color variations using Pantone references.
